Effects of Osseodensification on Primary Stability of Cylindrical and Conical Implants-An Ex Vivo Study. J Clin Med 2023; 12:jcm12113736. [PMID: 37297938 DOI: 10.3390/jcm12113736] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2023] [Revised: 05/23/2023] [Accepted: 05/26/2023] [Indexed: 06/12/2023] Open
Abstract
Primary stability is an important factor for dental implant success. In the past years, a new method for bone site preparation was introduced, named osseodensification (OD). OD produces a condensation of the trabecular portion of the bone, increasing bone-to-implant contact and primary stability. This study aims to compare the effect of OD in cylindrical and conical implants to conventional instrumentation. A total of forty implants, divided into four groups, were placed in porcine tibia: cylindrical conventional (1a), cylindrical OD (1b), conical conventional (2a) and conical OD (2b). Each implant was measured for implant stability quotient (ISQ), insertion torque (IT) and removal torque (RT). Group 2b showed the higher values for each of the evaluated parameters; groups 1b and 2b showed better results than 1a and 2a, respectively. Regarding the IT and RT, group 1b achieved higher values than group 2a, but not for ISQ. The inter-group comparison showed significant difference between groups 1a vs 2a, 1a vs 2b and 1b vs 2b for ISQ and 1a vs 1b and 1a vs 2b for RT analysis. OD resulted in improved ISQ, IT and RT of both cylindrical and conical implants.

Clin Implant Dent Relat Res 2022; 24:580-590. [PMID: 35950637 DOI: 10.1111/cid.13127] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2022] [Revised: 07/18/2022] [Accepted: 07/21/2022] [Indexed: 11/26/2022]
Abstract
AIM To evaluate the effect of special implant site preparation methods in improving primary implant stability in low-density bone. MATERIAL AND METHODS This meta-analysis included studies published in English and Mandarin Chinese up to March 31, 2022 from MEDLINE/PubMed, Embase, Scopus, and Wanfang databases. The primary stability of five site preparation methods were measured using implant stability quotient. The random-effects model was chosen for data analysis. Grading of recommendations assessment, development, and evaluation assessment was adopted as a collective grading of the overall body of evidence. RESULTS 12 of the 17 studies included in the meta-analysis were randomized control trials. Three studies investigated osseodensification drilling (OD), eight studies examined osteotome technique (OT), five studies explored piezosurgery (PS), and four studies were conducted on under-drilling (UD). Meta-analysis showed a statistically significant increase in primary stability for the OD (mean difference [MD], 10.25; 95% CI: 4.97-15.52; p < 0.001), OT (MD, 6.34; 95% CI: 2.26-10.42; p = 0.002), and UD (MD, 11.43; 95% CI: 5.17-17.68; p < 0.001) groups when compared to the conventional drilling group, while the PS group did not (MD, 1.50; 95% CI: -2.54-5.54; p = 0.47). CONCLUSION Significantly higher primary implant stability was shown in the OD, UD, and OT groups compared to the conventional drilling group. PS displayed the least favorable primary stability and when compared to conventional drilling, was not statistically significant.

The Effect of Under-Drilling and Osseodensification Drilling on Low-Density Bone: A Comparative Ex Vivo Study. APPLIED SCIENCES-BASEL 2022.

Abstract
The aim of this study is to identify a method that can maximize implant primary stability (IPS) and bone density under the controlled drilling conditions of the same diameter and length in low-density bones through an ex vivo study. A total of 87 dental implants were placed with standard drilling, under-drilling, and osseodensification drilling in 13 fresh porcine sternums. The Periotest value and the implant stability quotient were measured to evaluate the primary stability. The difference in the Hounsfield unit (HU) between the hole and peripheral bone up to a distance of 1 mm was measured. Osseodensification and under-drilling technique increased the IPS, compared with conventional drilling technique with statistical significance under the drilling conditions of the same diameter and length. Osseodensification technique with the counter-clockwise direction had higher HU gaps than the standard drilling and osseodensification technique with clockwise direction. Due to the effect of bone densification, the gap of HU was increased by a minimum of 43 HU and a maximum of 180 HU. Within the limitations of this ex vivo study, it was found that the osseodensification technique with counter-clockwise direction is effective to increase IPS and bone mineral density in low-density bone.
