Short Implants in Atrophic Posterior Maxilla

Short Implant Placement for Single-Tooth Rehabilitation in the Atrophic Posterior Maxilla

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.

Study Overview

• Status: Completed
• Conditions: Sinus Pneumatization; Bone Atrophy, Alveolar; Edentulism
• Intervention / Treatment: Procedure: implant placement

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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Clinical outcome	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).	2 years

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Rx outcome	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.	2 years
