Abstract

Purpose: The aim of this study is to compare the effects of two xenografts, i.e., porcine- and bovine-derived xenografts, on dental implant therapy after implant site development. Materials and Methods: This retrospective study involved adults who underwent dental implantation between January 2012 and December 2020. Various patient and implant-site characteristics were collected from the patient records. The implant-surgery clinical parameters of the porcine- and bovine-derived xenografts used for implant site development were analyzed and compared. Results: A total of 116 subjects with 168 dental implants were included in this study. There was less soft bone in the porcine bone group of the maxilla. However, there was less soft bone and a greater percentage of “primary stability ≥35 N” in the bovine bone group of the mandible. However, no significant differences in regrafting rate, post-operative infection rate, or implant survival rate were found between the bovine and porcine bone groups. Conclusion: The effects of implant site development using bovine- and porcine-origin xenografts are comparable in terms of the implant-therapy clinical parameters, including the regrafting rate and implant survival rate. Thus, the choice of xenografts could be made according to the patient’s religious requirements. However, the reported results should be used with caution, considering the limitations of this retrospective study.

Highlights

IntroductionBone regeneration is a common dental procedure, especially for the development of dental implant sites
Xenografts resorbed slower than calcium sulphate, beta-tricalcium phosphate, or allografts, xenografts preserved more bone volume when compared with calcium sulphate, beta-tricalcium phosphate, or allografts [1]
The results indicate that the developed ridge volumes of both groups may be similar; this finding agrees with the results of previous studies, which found that ridge preservation with porcine xenografts yields dimensional stability comparable to that of bovine xenografts [17,23]

Summary

Introduction

Bone regeneration is a common dental procedure, especially for the development of dental implant sites. Hydroxyapatite (HA) results in voids between the graft and bone tissue due to retention at the surgical site. Porous titanium granules and oxidized white porous titanium granules have better mechanical properties than deproteinized bovine bone mineral (DBBM). Early implant stability, osseointegration, and bone healing were not improved with the application of these mechanically stronger metal grafts [3]. Good bone quality could obtain a high primary stability value and increase the dental implant success rate. It is possible to enhance primary stability by specific techniques (e.g., osseodensification drill) in poor bone quality for implant success rate [4]
