Objectives
The objective of the retrospective study was to explore whether the use of a modified alveolar ridge preservation technique impacts osteogenesis on the distal surface of the second molar after mandibular third molar (M3) extraction.
Materials and methods
A total of 54 patients were enrolled in this study and divided into three different groups, including modified alveolar ridge preservation (MARP) group, traditional tooth extraction (TRA) group, and classical guided bone regeneration (GBR) group. In this study, MARP was designed with the highlights of the preservation of the alveolar bone superior and lingual to M3. These patients chose different surgical methods according to their own wishes for past infection or in order to prevent pericoronitis, and the operation time and surgical cost of each group were recorded. The periodontal conditions of the ipsilateral mandibular second molar (M2) and the height of its distal alveolar bone were measured during the postoperative follow-up.
Results
The probing depth, clinical attachment level, and osseous defect depth on the distal surface of the ipsilateral M2 in the MARP group were better than those of the TRA group at any time of the follow-up (P < 0.05 for all), but there was no statistical difference in the measurements when compared to the GBR group at 6 months after operation (P > 0.05 for all).
Conclusions
Thus, MARP therapy not only improves the regeneration of periodontal osseous defects distal to the M2 after M3 extraction but also reduces the operation time and surgical cost.
Clinical relevance
This paper introduces a modified surgical method that can not only economically and effectively remove the impacted mandibular third molar but also obtain stable osteogenesis.
