Abstract
OBJECTIVE Evaluate quantitative and qualitative outputs when comparing the incidence of platelet concentrates (PCs) combined with autogenous bone grafts to an autograft control group for the reconstruction of alveolar cleft defects. DESIGN Systematic review and meta-analysis. PATIENTS/PARTICIPANTS Randomized and nonrandomized controlled clinical trials where PCs were used in the reconstruction of alveolar cleft defects. INTERVENTIONS Use of PCs in combination with autogenous bone graft in the experimental group and autogenous bone graft alone in the control group. MAIN OUTCOME MEASURE(S) Average bone formation and bone density were evaluated, mean differences were calculated and pooled by a meta-analysis technique. Additionally, clinical outcomes such as wound dehiscence, closure of the oronasal fistula, pain, swelling, discharges, infections, and bleeding were considered in the qualitative synthesis. RESULTS After an evaluation of forty-nine articles, nineteen were considered for the review. The qualitative assessment of bone density, bone formation, and clinical outcomes showed no differences between groups in most of the included studies. The meta-analysis showed no statistical differences between PCs groups when compared to the control group in bone density at three months (mean difference 45.67 HU, P = .23) and six months (mean difference 48.57 HU, P = .64). Neither were statistical differences in the percentage of regenerated bone volume at six months (mean difference 6.39%, P = .15) and the volume of newly formed bone at 12 months (mean difference 0.37 mm3, P = .99). CONCLUSIONS There were no significant differences in terms of bone formation, bone density, and clinical outputs between groups.

Clin Oral Investig 2023; 27:4259-4270. [PMID: 37145153 PMCID: PMC10415484 DOI: 10.1007/s00784-023-05042-x] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2023] [Accepted: 04/24/2023] [Indexed: 05/06/2023]
Abstract
OBJECTIVE The essential concern of alveolar cleft grafting in patients of cleft lip and palate at the mixed dentition phase is to gain bone within the cleft area that provides closure of the oronasal communication with continuous and stable maxilla for future cleft teeth eruption or implantation. This study aimed to compare the effectiveness of mineralized plasmatic matrix (MPM) versus cancellous bone particles harvested from anterior iliac crest in secondary alveolar cleft grafting. PATIENTS AND METHODS This prospective randomized controlled trial was conducted on ten patients with unilateral complete alveolar cleft requiring cleft reconstruction. Patients were randomly divided into two equal groups; group (1) included 5 patients who received particulate cancellous bone derived from anterior iliac crest (control group) and group (2) included 5 patients who received MPM graft prepared from cancellous bone derived from anterior iliac crest (study group). All patients received CBCT preoperatively, immediately postoperatively and after 6 months. On the CBCT, graft's volume, labio-palatal width, and height were measured and compared. RESULTS The outcome of the studied patients 6 months postoperatively showed that the control group had significant decrease in the graft volume, labio-palatal width, and height compared to the study group. CONCLUSION MPM allowed for the integration of bone graft particles inside a fibrin network, which offers positional stability of the bone particles, thus preserving their shape with subsequent "in situ" immobilization of the graft components. This conclusion was reflected positively in terms of maintained graft volume, width, and height compared to that of the control group. CLINICAL RELEVANCE MPM allowed for maintenance of grafted ridge volume, width, and height.

Abstract
Our research aimed to investigate the effect of combining biphasic calcium phosphate (BCP) alloplast with mineralized plasmatic matrix (MPM) as compared with platelet-rich fibrin (PRF) on the quality and quantity of bone formation and maturation at surgically created horizontal critical-sized ridge defects (HRDs) in a canine model. We used a split-mouth design using the third and fourth mandibular premolars of the mongrel dogs. Twelve defects on the left side (experimental group, I) were managed with MPM composite mixed with BCP alloplast, MPM compact layer. On the right side (control group, II), another 12 defects were managed with PRF mixed with BCP alloplast, followed by the application of PRF compact strips. Finally, both were covered by a collagen membrane. Dogs were euthanized at 4, 8, and 12 weeks, and the studied defects were processed to evaluate treatment outcome, including mean percentage of bone surface area, collagen percentage, and osteopontin (OPN) immunoreaction. Our results revealed that the mean percentage of bone surface area was significantly increased in the experimental group treated with MPM at all time intervals as compared with the PRF group. Decreased collagen percentage and increased OPN immunoreactivity showed significant results in the MPM group as compared with PRF at 4 and 8 weeks postoperatively, respectively. In conclusion, MPM accelerates the formation of superior new bone quality when used in the treatment of HRDs.

Abstract
Objectives: The purpose of this study is to assess the effectiveness of mineralized plasmatic matrix in the soft tissue closure of naso-alveolar fistula, to estimate the postoperative bone fill and volume of the graft placed in the alveolar cleft defect using cone-beam computed tomography (CBCT) at 3rd- month and 6th- month. Material and methods: 10 patients, in the age group of 15‑30 years were included in this study. They were diagnosed with unilateral cleft lip and alveolus defects with or without a cleft palate requiring late secondary alveolar bone grafting. Alveolar cleft defects were closed with mineralized plasmatic matrix (MPM), a combination of autogenous iliac bone graft and platelet rich plasma (PRP) and platelet rich fibrin (PRF). Results: The mean defect volume pre-operatively is 0.75 cm3 and at the end of 3rd-month postoperatively is 0.51 cm3 and at 6th-month postoperatively is 0.27 cm3. The average percentage of bone fill between preoperative (A) & 3th- month postoperatively (B) is 33.4% and between 3rd-month (B) and 6th-month post operatively (C) is 49.5%. Conclusions: Utilization of this new matrix (MPM), has shown to be effective in the closure of the cleft defect, oro-nasal fistula and also reduction in the volume of the residual cleft defect seen with sequential cone-beam computed tomography (CBCT) radiographs.

Abstract
BACKGROUND The oronasal fistula in cleft patients is one of the complications that can be found after primary surgeries due to a failure of healing of the surgical repair that causes the communication between the oral and nasal cavities. A number of procedures can be implemented to correct the fistula and it is not clear if a particular technique is the best to be recommended. OBJECTIVE This study aims to systematically analyze the scientific evidence regarding the treatment of oronasal fistulas located in the lingual-alveolar and labial-alveolar regions in patients with cleft lip and palate who have undergone primary surgeries. MATERIAL AND METHODS A bibliographic search of articles published until September 2018 without restricted year and language of publication, in PubMed (Medline), Scopus, Cochrane, Web of science, and BVS databases. The MeSHterms "Fistula," "Oral Fistula," and "Cleft Lip" were used, which were related to each other and with other keywords related to the subject of the review through the "OR" and "AND" operators. The quality of the publications was evaluated according to the guidelines of the Methodological Index for Nonrandomized Studies. RESULTS After applying the eligibility criteria, a total of 18 articles were selected for the extraction of data and qualitative analysis. CONCLUSION All publications analyzed in this review reported the fistula treatment at the same surgical time as the bone graft, independently of the donor area, the type of cleft treated and the patient's age at operation. There was no consensus among the studies on the best treatment type for oronasal fistulas located in the alveolar region, and further comparative studies between the existing techniques will be necessary to address this question.

Abstract
Background:
Mineralized Plasmatic Matrix [MPM] is a unique form of platelet rich fibrin that contains mineralized bone graft particles within a fibrin network.
Aim:
This study was conducted to evaluate horizontal ridge augmentation using MPM with and without a coverage membrane.
Materials and Methods:
Sixteen edentulous spaces were randomly divided into 2 equal groups. MPM was used for horizontal ridge augmentation with and without a covering collagen membrane (group 1 and 2, respectively). Cone Beam CT images were obtained preoperatively as well as 1 week and 4 months postoperatively to evaluate alveolar ridge and the resorption of the grafting material at 3 predetermined points along with the site where the future dental implant will be placed.
Student’s t-test (Unpaired) was used for comparing two different groups with quantitative parametric data and student’s t-test (Paired) was used for comparing two related groups with quantitative parametric data while repeated measures ANOVA (Analysis of variance) followed by post-hoc Bonferroni was used for comparing more than two related groups with quantitative parametric data.

Abstract
The aim of this study was to analyze the newly formed bone volume (FV), 6 months after secondary alveoloplasty using iliac cancellous bone graft, with and without platelet-rich plasma (PRP). Forty patients with unilateral alveolar cleft were involved in this randomized, prospective, comparative study, with 20 patients each forming the control (group A) and PRP (group B) groups, respectively. The preoperative alveolar defect volume (DV) and the postoperative FV were automatically calculated by the computer-aided engineering software using the patients' pre and postsurgical computed tomography data. The volume of the actual bone graft (AV) was identical to the DV calculated before surgery. The bone formation ratio (BF%) was calculated as follows: BF% = (FV/AV) × 100%. The mean BF% was 42.54 ± 9.32% in group A and 46.97 ± 18.49% in group B. There was no statistically significant difference between the 2 groups for BF% (P > 0.05). The study presents a fast and accurate method for assessing the effect of PRP in alveolar grafting. However, the study found no conclusive evidence on the effect of PRP on bone growth.

Abstract
Preservation of the alveolar bone is a determinant in the outcome of orthodontic treatment. Alveolar bone defects or a decrease of their height and width may occur due to common reasons such as inflammation, tooth extraction, or cleft lip and palate. The aim of this systematic review was to investigate and appraise the quality of the most up to date available evidence regarding the applications and effects of platelet-rich fibrin (PRF) in orthodontics. This study was carried out according to preferred reporting items for systematic reviews and meta-analyses guidelines using the following databases: Medline via PubMed, Cochrane Library, Web of Science Core Collection and EMBASE. The qualitative assessment of the included studies was performed using Cochrane Risk of Bias tool and ROBINS-I guidelines. Results: From a total of 489 studies, nine studies were selected. The majority of the included studies demonstrate that autogenous anterior iliac graft with PRF had a higher amount of newly formed bone. Furthermore, this review also suggests that the application of platelet derivatives in the extraction socket can accelerate orthodontic tooth movement. Despite the limitations in the included studies, this systematic review suggested that PRF can improve alveolar cleft reconstruction and orthodontic tooth movement.

Abstract
OBJECTIVE The aim of this study was to evaluate the effect of mineralized plasmatic matrix (MPM), comprising a combination of synthetic graft and platelet concentrates, on bone regeneration. METHODS Critical size defects of 6-mm diameter were created on the tibias of 6 male sheep, with the animals subsequently assigned into 2 groups. Of the 5 bone defects generated per animal, 4 were randomly filled with MPM, beta-tricalcium phosphate graft (β-TCP), platelet-rich fibrin (PRF) + β-TCP, and autogenous graft. One defect was left empty as a control group. Animals were killed at 3 weeks (early healing group) and 6 weeks (late healing group). The specimens underwent histologic and histomorphometric analysis to evaluate new bone formation. RESULTS In both healing periods, new bone formation from autogenous bone was observed significantly more often than from biomaterials or the empty defect. The degree of new bone formation for MPM was significantly higher than that of the control group at all healing periods. In addition, it was significantly higher in both healing periods than that of β-TCP albeit only in the late healing period than that of the PRF + β-TCP combination. In all biomaterial groups, residual graft ratios decreased from early to late healing periods. CONCLUSION The results indicated that MPM, representing growth factors in a fibrin network, increases new bone formation in surgically created defects in sheep tibia as confirmed by histologic assessment.

Abstract
PURPOSE OF REVIEW Cleft lip and palate still remains one of the most common congenital anomalies, and consequently surgical correction of these anomalies is still commonplace. Despite numerous existing surgical techniques having good outcomes, it is still recognized that the morbidity of certain surgical procedures and success rates regarding outcomes can be improved. The purpose of this review is to evaluate new literature and techniques compared with the time tested procedures that are commonly used. RECENT FINDINGS As technology continues to advance, the understanding of details regarding biochemical pathways responsible for the development of cleft defects and also the efficacy of biomaterials that can be used in their correction are being discovered and better understood. Many studies have been conducted in both animal and human study participants that further the understanding of these questions. The efficacy and benefit of newly devised biomaterials seems to indicate that these biomaterials are a viable adjunct and often an alternative in the treatment of cleft palate patients. SUMMARY In this review of recent literature, the discussion begins with a review of the more traditional and widely accepted iliac crest bone grafting and then evolves into a discussion of several animal and human studies to delineate the progress being made in this field. The literature exploring the details regarding biochemical pathways and cellular mediators that are involved in cleft formation, as well as biomaterials used in surgical repair are evaluated. The findings in the literature suggest that there is a bright future in better understanding the cause of cleft formation on a molecular level and associated attempts that can be made in altering some of these factors along with discovering new biomaterials that can be a useful adjunct to existing techniques.

Abstract
The aim of the present investigation was to systematically analyse the literature on the facial bone reconstruction defect using marine collagen or not and to evaluate a predictable treatment for their clinical management. The revision has been performed by searched MEDLINE and EMBASE databases from 2007 to 2017. Clinical trials and animal in vitro studies that had reported the application of bone substitutes or not for bone reconstruction defect and using marine collagen or other bone substitute material were recorded following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The first selection involved 1201 citations. After screening and evaluation of suitability, 39 articles were added at the revision process. Numerous discrepancies among the papers about bone defects morphology, surgical protocols, and selection of biomaterials were found. All selected manuscripts considered the final clinical success after the facial bone reconstruction applying bone substitutes. However, the scientific evidence regarding the vantage of the appliance of a biomaterial versus autologous bone still remains debated. Marine collagen seems to favor the dimensional stability of the graft and it could be an excellent carrier for growth factors.

Effect of Bone Regeneration with Mineralized Plasmatic Matrix for Implant Placement in Aesthetic Zone. Case Rep Dent 2017; 2017:2639564. [PMID: 28458929 PMCID: PMC5387826 DOI: 10.1155/2017/2639564] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2016] [Revised: 02/26/2017] [Accepted: 03/08/2017] [Indexed: 11/17/2022] Open
Abstract
Bone volume is one of the key factors to be considered when evaluating implant placement. When the bone volume is insufficient, implant placement could be conditioned by the necessity of preforming bone grafting procedures to compensate bone loss. Various grafting procedures can be used with different bone substitute. Mineralized Plasmatic Matrix (MPM) is one of these grafting materials, used to maintain or regenerate the socket's volume. In MPM, the autologous blood products highly concentrated in platelets and fibrin in a liquid state are combined with a bone substitute. The fibrin can become bound to bone particles. The filling material is easy to shape and a PRF-type membrane is also generated. In the present case we report the application of MPM in two sites presenting bone crest defects when placing implant in those areas.
