Abstract

Introduction: Nowadays, the final success of implantation is not only based on obtaining osseointegration of the implant but is also determined by achieving a satisfactory aesthetic effect of the soft tissues surrounding the implant, which can be defined as an aesthetic integration. The process of obtaining this aesthetic integration already begins at the stage of placing the healing abutment, which allows us to obtain the emergence profile necessary for our prosthetic reconstruction. Materials and Methods: The study used cone-beam computer tomography (CBCT) scans of 51 patients. The measurements of the maxillary teeth (central incisor, lateral incisor, canine, first premolar, and first molar) were performed from cross-sections of the individual teeth at the transition zone to design a custom anatomic healing abutment milled from zirconium and luted to the non-index Ti-base. Results: The obtained results allowed to design and create the shape of the anatomic healing abutment. Conclusions: The use of laboratory-produced anatomical healing abutments is possible and may allow to obtain the desired and planned emergence profiles of prosthetic restorations. In addition, it might be a method of reducing work time at the dental chair but further clinical trials are necessary.

Highlights

Nowadays, the final success of implantation is based on obtaining osseointegration of the implant but is determined by achieving a satisfactory aesthetic effect of the soft tissues surrounding the implant, which can be defined as an aesthetic integration.The process of obtaining this aesthetic integration already begins at the stage of placing the healing abutment, which allows us to obtain the emergence profile necessary for our prosthetic reconstruction
The received results allowed to design the shape of the individualized anatomical healing abutment for each group of the teeth mentioned (Table 1)
In order to achieve success in implantology treatment, it is highly beneficial to understand the importance of proper designing and the obtaining of the emergence profile

Summary

Introduction

The final success of implantation is based on obtaining osseointegration of the implant but is determined by achieving a satisfactory aesthetic effect of the soft tissues surrounding the implant, which can be defined as an aesthetic integration.The process of obtaining this aesthetic integration already begins at the stage of placing the healing abutment, which allows us to obtain the emergence profile necessary for our prosthetic reconstruction. Current guidelines for successful therapeutic implantology treatment are based on the evaluation of the implant and restoration survival, dento-gingival aesthetics, rate of mechanical complications, and the bone levels and health of surrounding soft tissues [1,2,3]. A transmucosal attachment is created: an attachment of soft tissues connecting to the implant and providing a barrier between the oral environment and bone tissue. The cause of bone resorption around the implant is not from strain but from the exposure to the oral environment, as it occurs regardless of whether the implant is tightened with a connector, crown, or healing abutment [4]
