Survival of Implants after Indirect Maxillary Sinus Elevation Procedure: A Two Years Longitudinal Study

Area of Science:

• Dental Implantology
• Biomaterials Science
• Oral Surgery

Background:

• Osseointegration is crucial for dental implant success.
• Implant surface characteristics significantly influence osseointegration.
• Optimal implant surface macrotopography remains debated in scientific literature.

Purpose of the Study:

• To evaluate and compare the survival rates of two distinct dental implant systems.
• To assess the impact of different implant surfaces on clinical and radiographic success.
• To investigate the association between implant surface type and osseointegration outcomes.

Main Methods:

• A cohort of 150 patients received dental implants via indirect sinus floor elevation.
• Implants were categorized into two groups (Group A: 100, Group B: 50) based on distinct implant systems and surfaces.
• Clinical, radiographic examinations, and infection assessments were conducted periodically, with annual follow-ups.

Main Results:

• Chi-square analysis revealed no statistically significant association between implant surface type and implant success or failure rates.
• Both implant systems (Group A and Group B) exhibited comparable clinical success.
• No significant difference was observed in the success rates between the implant groups, indicating surface type did not influence outcomes.

Conclusions:

• While surface treatments can enhance osseointegration, this study found no significant difference in survival rates between the evaluated implant surfaces.
• Both bioetched and Tiunite implant surfaces achieved clinical success.
• Further case-controlled studies with extended follow-up are recommended to validate these findings on implant surface efficacy.
