CLINICAL OUTCOMES OF A NOVEL TECHNIQUE IN IMMEDIATE IMPLANT PLACEMENT IN MOLARS USING TOOTH PLANNED FOR EXTRACTION AS GUIDE

Abstract

This retrospective study aimed to evaluate the clinical outcomes of a novel immediate implant placement technique in molar teeth using the extracted tooth as a guiding structure for osteotomy preparation, with a minimum follow-up period of 6 months. Clinical parameters assessed included pain, suppuration, implant mobility, plaque index, bleeding on probing, probing depth, keratinized mucosa, marginal bone loss, and implant success. Angular deviations of implant placement were also analyzed and compared with freehand implant placement. A total of 11 implants placed between 2022 and 2025 were included in the analysis. During the follow-up period, no patients exhibited pain, suppuration, or implant mobility. The mean plaque index was 0.32 ± 0.43, and the mean bleeding on probing score was 0.73 ± 0.51. Probing depths £ 4 mm were observed in 36.36% of implants, whereas 63.64% exhibited probing depths greater than 4 mm. Adequate keratinized mucosa was present in 81.82% of implants, with no cases of gingival recession. Radiographic evaluation demonstrated marginal bone loss ranging from 0.12 to 1.79 mm mesially and from 0.03 to 1.98 mm distally. The implant success rate was 100%. Mean angular deviations were 4.73 ± 3.17 degrees in the mesiodistal direction and 3.36 ± 2.79 degrees in the buccolingual direction. Compared with freehand placement, a significant reduction in mesiodistal angular deviation was observed, while no significant difference was found in buccolingual deviation.
