Abstract

Background

This retrospective study aimed to assess the impact of maxillary and mandibular autogenous bone grafts on maxillary bone height in patients who underwent maxillary sinus floor elevation (MSFE).

Methods

The study involved 92 patients, divided into two groups: 37 patients receiving maxillary bone grafts for MSFE and 55 patients receiving mandibular bone grafts for MSFE. Bone height after MSFE was measured on panoramic radiographs up to 60 months postoperatively, comparing different positions and situations.

Results

In general, both maxillary and mandibular bone grafts resulted in an increase in bone height directly after the MSFE procedure, followed by a bone height loss over time, with no significant differences between the two groups for gap and free-end positions. However, at distal to implant positions, mandibular bone grafts showed less bone loss. Despite gradual bone height loss, all implants remained covered with bone without exposure or subsequent loss, indicating a successful MSFE procedure.

Conclusion

This radiologic study showed that over a long-term period there is a similar bone height pattern at dental implant sites and sites distal to implants when maxillary or mandibular bone grafts are used in MSFE.

期刊介绍： The goal of Clinical Implant Dentistry and Related Research is to advance the scientific and technical aspects relating to dental implants and related scientific subjects. Dissemination of new and evolving information related to dental implants and the related science is the primary goal of our journal. The range of topics covered by the journals will include but be not limited to: New scientific developments relating to bone Implant surfaces and their relationship to the surrounding tissues Computer aided implant designs Computer aided prosthetic designs Immediate implant loading Immediate implant placement Materials relating to bone induction and conduction New surgical methods relating to implant placement New materials and methods relating to implant restorations Methods for determining implant stability A primary focus of the journal is publication of evidenced based articles evaluating to new dental implants, techniques and multicenter studies evaluating these treatments. In addition basic science research relating to wound healing and osseointegration will be an important focus for the journal.
