Short Implants in Atrophic Posterior Maxilla

Not Applicable

Completed

• Conditions: Edentulism; Bone Atrophy, Alveolar; Sinus Pneumatization

• Registration Number: NCT06759246
• Lead Sponsor: University of Bari Aldo Moro

Brief Summary

This study aims to evaluate the clinical and radiological outcomes of short implants in the rehabilitation of single-tooth edentulism in the posterior maxilla. By assessing these outcomes, the research seeks to determine the effectiveness and long-term viability of short implants as a minimally invasive solution, particularly in cases where bone height is limited.

Detailed Description

The present municentric retrospective study was conducted following the STROBE statement recommendations for observational studies and in compliance to the principles of the Declaration of Helsinki on clinical research involving human subjects.The study aims to evaluate short implants placed over the past 15 years by three experienced clinicians, assessing their survival and clinical success. Specifically, the study collects clinical data such as probing depth, the presence or absence of peri-implantitis, and radiological findings.

• Study Design: SINGLE_GROUP

Primary Outcome Measures

Name	Time	Method
Clinical outcome	2 years	Survival rate: A statistical analysis will be conducted to evaluate the implant survival rate at three specific time points: T1 (3 months), T2 (6 months), and T3 (2 years).

Secondary Outcome Measures

Name	Time	Method
Rx outcome	2 years	Radiographic measurements will be obtained using standardized imaging techniques. The measurements will be performed digitally using dedicated three-dimensional radiological imaging software, ensuring high precision. Distances will be measured in millimeters to evaluate implant positioning, bone levels, and defect morphology with accuracy.
