Immediate Post-Extractive Single Implant in the Molar Region Using Two Different Healing Abutments: A Randomized...

Area of Science:

• Dental Implantology
• Periodontology
• Biomaterials Science

Background:

• Immediate implant placement offers functional and esthetic advantages.
• Maintaining marginal bone stability is crucial for long-term implant success.
• Conventional healing abutments may not always optimize the peri-implant soft and hard tissue environment.

Purpose of the Study:

• To compare marginal bone loss in immediately placed molar implants using customized versus conventional healing abutments.
• To assess the impact of abutment type on peri-implant bone levels at 12 months post-placement.

Main Methods:

• Prospective randomized controlled clinical trial with 36 patients and 36 immediate molar implants.
• Group A: Customized healing abutments; Group B: Conventional healing abutments.
• Radiographic assessment of marginal bone level changes at 12-month follow-up; statistical analysis using linear regression models.

Main Results:

• No significant difference in implant survival rates (94.11%) between groups.
• Significantly lower mean marginal bone loss in the customized abutment group (0.51 ± 0.42 mm) versus the conventional group (1.34 ± 0.75 mm) (p < 0.001).
• No assessed covariates significantly influenced bone loss.

Conclusions:

• Customized healing abutments may enhance peri-implant marginal bone stability in immediate molar implant placements.
• This approach could lead to improved long-term treatment outcomes and successful osseointegration.
• Customized abutments represent a promising strategy for optimizing immediate molar implant success.
