Abstract

Aim: The purpose of the present study is to evaluate the bone volume and quality formed following graftless maxillary sinus lifting through lateral window approach to compare the efficiency of the use of titanium screws versus the use of titanium mesh in preserving the space below the uplifted maxillary sinus membrane allowing for stable blood clot formation in severly atrophied posterior maxillary ridge. Subjects and Methods: The current study include 10 maxillary sinuses, The study patients were partially or completely edentulous in the posterior maxilla and required unilateral or bilateral maxillary sinus augmentation. All patients were selected from the out-patient clinic of Oral and Maxillofacial Surgery Department, faculty of oral and dental medicine, Cairo University. Results: The sinuses were divided into two equal groups (study and control groups), both groups underwent maxillary sinus lift procedures using either space-maintaining titanium screws for the study group or space-maintaining titanium mesh for the control group. The study was a double blind one (participants and outcome assessors were blinded throughout the study). Conclusion: application of titanium mish with micro screws to support the sinus membrane was easier clinically than using long titanium screws alone, as the accessibility and direction of drilling was more difficult when long titanium screws were used

Highlights

Mesh and screws placement In control group : 0.1 mm thickness micro titanium mesh was cut and its sharp projections were smoothed it bent as S- Shape it was fixed to the lateral wall of the sinus above the superior osteotomy with two 1.5mm micro screws
Linear Measurements Descriptive statistics showing mean values, standard deviations (SD), standard error of mean (SEM), median and range for alveolar bone height measured in recorded for both groups as function of evaluation periods summarized in table (1) and graphically represented in figure (3)
Bone density Descriptive statistics showing mean values, standard deviations (SD), standard error of mean (SEM), median and range for bone density measured in (HU) recorded for both groups as function of evaluation periods summarized in table (1) Bone volume Table (2) shows the means and SD values of bone volume

Summary

Introduction

Restoration of the atrophied edentulous posterior maxillary region is considered one of the most significant challenges that face the Oral and Maxillofacial surgeon as well as the restorative dentist. In the study group: 2.0 mm screws were fixed to the lateral wall of the sinus above the superior osteotomy and placed buccopalatally where the schneiderian membrane was elevated and maintained
