Comparative evaluation of clinical and radiographic outcomes of three different techniques used for membrane elevation in indirect sinus lifting a randomized controlled trial

Abstract

The implant surgeon is often faced with the challenge of deficient residual newlinebone height when planning for implants in the posterior maxilla. Fortunately, newlinethe most well documented and reliable technique of bone augmentation are newlinethe maxillary sinus augmentation techniques. The success of any sinus lift newlineprocedure lies in the successful elevation of the delicate membrane without newlineany perforations. However, it is a blind procedure for which a reliable newlinetechnique is essential. The goal of each technique is to provide a simple and newlinereliable technique of safe elevation of the sinus membrane. newlineAIM newlineTo compare the clinical and radiographic outcomes of three different newlinetechniques used for membrane elevation in Indirect Sinus Lifting. newlineMATERIALS AND METHODS newlineThis study was undertaken over a time period of 1 year between March 2021 newlineto February 2022 in the department of Oral Implantology, SDC. Ethical newlineapproval for performing the study was obtained. The inclusion criteria were newlinethose patients that had a RBH of 7mm to 10mm and were indicated for newlineimplant placement with an indirect sinus lift for the placement of 10mm newlinelength endosseous implants. Systemically compromised patients, newlineperiodontally compromised patients, patients having thickening of sinus newlinemembrane and sinus pathology were excluded. Patients with symptoms of newlineacute sinusitis or a cold on the day of surgery were asked to report back newlinewhen they were symptom free. The 3 membrane elevation techniques newlineemployed in this study were Hydraulic lift group (Group1), newlineOsseodensification group (Group2) and Osteotome group(Group3). The newlineoutcome measures evaluated were primary stability (ISQ), VAS, time taken, newlineendo sinus bone gain and complications. CBCT analysis was done to record newlinethe values of endo sinus bone gain. Statistical analysis tests were done to newlinecalculate the mean of all the outcome measures. Wilcoxon Signed rank test newlinewas done for intragroup comparison and Kruskal-Wallis test was done for newlineintergroup comparison. newline
