Smart Digital Denture Conversion (SDDC), a Technique for Full Arch Immediate Loading

Ain Shams University30 enrolled

Overview

This study presents a smart digital approach to design and construct a screw retained immediately loaded full arch implant supported bridge based on the pre-treatment complete denture.

After intra oral scanning of the ridge form, implant positions, the denture is used to scan the intermaxillary relation and tooth positions and the fixed interim is designed and milled from PMMA. This technique is applicable when a single arch is treated or for bimaxillary implant rehabilitation cases. In this study 30 patients were grouped into two groups; group I in which a converted denture was made conventionally and Group II in which a converted denture was made digitally. General satisfaction, chair side working time, and esthetic outcome of the prostheses were recorded and quantified with a verbal rating scale following insertion of implant-supported prosthesis.

conventional denture conversionPROCEDURE

conventional workflow usually done to do immediate loading for full arch implant cases

digital denture conversionPROCEDURE

An alternative workflow for construction of the fixed interim requires impressions, model production, and jaw relation records then digitizing all these data then designing and milling the restoration.

Outcomes

Primary Outcomes

Patient general satisfaction questionnaire

General satisfaction with a verbal rating scale range from 0 to 5, as 0 denotes the lowest value (worst) and 5 the highest value (best), following insertion of implant-supported prosthesis.

Time frame: through study completion within 6 months

Secondary Outcomes

chair side working time questionnaire

the procedure working time with a verbal rating scale range from 0 to 5, as 0 denotes the lowest value (worst) and 5 the highest value (best), following insertion of implant-supported prosthesis.

Time frame: through study completion within 6 months

esthetic satisfaction questionnaire

esthetic outcome of the prostheses with a verbal rating scale range from 0 to 5, as 0 denotes the lowest value (worst) and 5 the highest value (best), following insertion of implant-supported prosthesis.

Time frame: through study completion within 6 months
