Abstract

Objective: To evaluate the improvement in masticatory performances two weeks after posterior implant restoration. Material and Methods: Nine patients with missing first and second molars were included in the study. Masticatory performances were evaluated using subjective and objective methods utilizing color-changeable chewing gum and the visual analog scale (VAS) assessment. The subjects were asked to chew the color-changeable chewing gums before and two weeks after the posterior implant restoration. Their expectations regarding aesthetics and function were verified on the VAS before implant placement. Additionally, the VAS was used for the posttreatment completion rating two weeks after the implant restoration . Results: Significant differences in masticatory performance were noted at baseline (before implant posterior restoration) and two weeks after implant restoration (p<0.05). The posttreatment aesthetic and functional expectations ratings significantly exceeded the expectations (p<0.05) . Conclusion: Masticatory performances were improved two weeks after implant restoration. In addition, the significant posttreatment ratings of the patients exceeded their initial expectations. In particular, patients with poor masticatory functions demonstrated significant improvements and satisfaction following implant restoration compared to those with good mastication. These findings indicate that a posterior implant restoration can increase the masticatory performance.

Highlights

With the increase in the average life span, people are becoming increasingly aware of maintaining the quality of life, including the dietary lifestyle [1]
A 10% increase in masticatory performance was observed two weeks after the implant restoration compared with the edentulous state before implant placement
This study confirmed that masticatory performance, as evaluated subjectively using the visual analog scale (VAS) and objectively using the color-changeable chewing gum method, could increase two weeks after implant restoration

Summary

Introduction

With the increase in the average life span, people are becoming increasingly aware of maintaining the quality of life, including the dietary lifestyle [1]. Clinicians and patients are looking for implant options that can reduce the procedure's invasiveness or increase the speed of osseointegration [1]. SLActive surfaces are produced with the same sandblasting and acid-etching technique; they are rinsed under nitrogen protection to prevent air exposure and stored in a sealed glass tube containing isotonic sodium chloride (NaCl) solution. Schwarz claimed that this specific preparation process leads to a hydroxylated/hydrated surface, which retains the high surface energy by reducing the adsorption of potential contaminants from the atmosphere (e.g., hydrocarbons and carbonates). The SLActive surface allows for fast and predictable osseointegration enabling a safer and faster treatment method with high treatment predictability [4]
