Treatment efficiency and stability of skeletal Class III malocclusion with a surgery-first approach

Short-term treatment of skeletal class III malocclusion by surgery-first approach with SDU protocol

The aim of this case series is to present the successful treatments and long-term results of three adult skeletal class III patients treated with the surgery-first (SF) approach by applying the SDU (Suleyman Demirel University) protocol and to discuss the differences, advantages and disadvantages compared with other methods. Although there were differences in the treatment planning and surgical procedures of the three patients in the case series, the same protocol was followed in all three patients. The desired aesthetic result and functional occlusion were achieved with the SF approach. Significant improvement was observed in the patients' profile and facial appearance in a short time. The total duration of treatment for all cases was less than a year.

Does a surgery first approach to orthognathic treatment of class III skeletal relations result in a shorter duration of treatment? A systematic review

The objective of this study was to review the evidence relating to treatment duration and the surgery first approach (SFA) in managing class III skeletal discrepancies to determine whether there is sufficient evidence to show that it results in a shorter duration of treatment compared to a conventional orthodontics first approach (OFA). Analytical and observational studies that compared both approaches and recorded treatment duration as an outcome were included. MEDLINE, EMBASE, CENTRAL and Dental Oral Sciences Source databases were searched along with a review of reference lists. Risk of bias was assessed using the Risk of Bias in Non-randomised Studies of Interventions (ROBINS-I) tool. Eleven observational studies met the inclusion criteria. No experimental studies were identified. The SFA was reported to have a shorter duration of treatment in all studies. All included studies showed a significant risk of bias, particularly in relation to selection of participants, allocation to groups and in the measurement of treatment duration. There is no quality evidence to suggest that using a surgery first approach to orthognathic treatment of class III skeletal patterns results in a shorter duration of treatment.

Changes in the temporomandibular joint clicking and pain disorders after orthognathic surgery: Comparison of orthodontics-first approach and surgery-first approach

The purposes of this study were to investigate the influence of the orthodontics-first approach (OFA) and surgery-first approach (SFA) on changes in the signs and symptoms of temporomandibular joint disorders (TMDs) and to compare pre- and postoperative orthodontic treatment duration and total treatment duration between the two approaches. This retrospective study recruited 182 adult patients with malocclusions treated with OFA and SFA and recorded variables such as age, gender, skeletal classification, and signs and symptoms of TMD (clicking and pain disorders) before the start of the surgical-orthodontic treatment and after surgery. Changes in the signs and symptoms of TMD and treatment duration were evaluated within each approach and compared between two approaches. A binary logistic regression was performed to assess the influence of the variables on the postoperative signs and symptoms of TMD. There were no significant postoperative changes in temporomandibular joint (TMJ) pain for OFA and SFA, whereas a significant reduction was found in TMJ clicking after surgery for both approaches. According to binary logistic regression, the type of surgical-orthodontic treatment (OFA or SFA) was not a significant risk factor for postoperative TMJ clicking and pain, and the risk of postoperative TMJ clicking and pain was significant only when TMJ clicking (OR = 10.774, p < 0.001) and pain (OR = 26.876, p = 0.008) existed before the start of the entire treatment, respectively. With regard to the treatment duration, SFA (21.1 ± 10.3 months) exhibited significantly shorter total treatment duration than OFA (34.4 ± 11.9 months) (p < 0.001). The results of this study suggest that surgical-orthodontic treatment using SFA can be a feasible option of treatment for dentofacial deformities based on the equivalent effect on TMD and shorter overall treatment period compared to conventional surgical-orthodontic treatment using OFA.

Treatment of an Adult Skeletal Class III Patient with Surgically Assisted Rapid Palatal Expansion and Facemask

This case report presents the treatment of a 21-year-old male patient with class III skeletal malocclusion, an open bite, and vertical growth pattern. He was managed with surgically assisted rapid palatal expansion (SARPE) along with an orthopedic facemask. The duration of treatment was 16 months. Significant improvement and favourable outcome were observed concerning both facial appearance and paraclinical parameters after completion of treatment.

Surgery-first orthognathic approach: A “scoping review” for mapping outcomes and plausible recommendations to develop core outcome sets

Aims and Objectives

The aim of this scoping review was to identify the type of outcomes measured in surgery- first orthognathic approach (SFOA). The objectives were to classify the outcomes into predetermined domains and explore the degree of representation of each domain. Furthermore, to identify which domains are over- or under-represented and determine whether the findings of this scoping review could be employed to provide a template for core outcome sets (COS). Five outcomes were identified, and all the research pertinent to SFOA were assigned to these outcomes.

Materials and Methods

Electronic databases and additional records were searched from January 2009 to March 2019 to source the data, and 525 records were identified.

Results

The initial database and additional search resulted in 525 records, of which 54 potentially relevant articles were retrieved in full. 35 studies met the selection criteria following screening and were included in the scoping review with the results of the search depicted in the preferred reporting items for systematic reviews and meta-analyses. Domains such as morphological features or changes in maxillofacial skeleton and occlusion (n = 25, 71.42%) and psychosocial well-being including quality of life outcome (n = 8, 22.85%) were well represented while functional status (n = 1, 2.85%), health resource utilization (n = 0), and adverse effects (n = 1, 2.85 %) were under-represented.

Conclusions

Limited research on SFOA precludes development of COS. However, future SFOA clinical trials should consider underrepresented outcome domains to address the SFOA treatment modality comprehensively.
