用于狭窄牙槽嵴扩增的骨挤压术 (OD-RridgeExp)

实验性的：osseodensification Group

Participants with healed edentulous sites and limited horizontal alveolar ridge width underwent dental implant-site preparation using the osseodensification technique. Baseline ridge-width measurements were obtained using standardized Micro Castroviejo bone calipers at the crestal level and at 5 mm and 10 mm apical to the crest. Following osseodensification-assisted osteotomy preparation, ridge-width measurements were repeated at the same reference levels before implant insertion.

程序：Densah burs (Osseodensification Technique)

Dental implant osteotomies were prepared using sequential osseodensification burs operated in counterclockwise densifying mode under copious irrigation. The burs were advanced using a controlled pumping motion according to the study protocol. Ridge width was measured immediately before and after completion of the osteotomy at three predefined levels, followed by dental implant placement and insertion-torque recording.

Change in Alveolar Ridge Width Following Osseodensification

Change in alveolar ridge width, measured in millimeters, using standardized Micro Castroviejo bone calipers at three predefined reference levels: (1) the crestal bone level, (2) 5 mm apical to the crest, and (3) 10 mm apical to the crest.

Measurements were obtained immediately before osteotomy preparation and immediately after completion of osseodensification-assisted osteotomy preparation, before implant insertion. The outcome was calculated separately at each level as the post-osseodensification measurement minus the corresponding baseline measurement.

Insertion Torque at Dental Implant Placement

Primary mechanical implant stability was assessed by recording the maximum insertion torque, measured in Newton-centimeters (Ncm), at the time of dental implant placement following osseodensification-assisted osteotomy preparation.

Occurrence of Postoperative Clinical Complications

The occurrence of recorded postoperative clinical events was assessed after implant placement. Events included pain, edema, infection, paresthesia, supuration, and other clinically documented complications. Each event was recorded using the prespecified study definitions and reported using the number of participants and implant sites with available follow-up data.

Agreement Between Baseline CBCT and Direct Clinical Caliper Measurements

Agreement between preoperative CBCT-derived alveolar ridge-width measurements and direct intraoperative baseline measurements obtained using Micro Castroviejo bone calipers was assessed at the crestal level and at 5 mm and 10 mm apical to the crest.

The comparison included paired differences, rank correlations, and descriptive Bland-Altman limits of agreement. The analysis assessed baseline measurement correspondence and did not compare postoperative caliper measurements with postoperative CBCT.
