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

Not Applicable

Completed

• Conditions: Complete Edentulism
• Interventions: Procedure: digital denture conversion; Procedure: conventional denture conversion

• Registration Number: NCT06233552
• Lead Sponsor: Ain Shams University

Brief Summary

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.

Detailed Description

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.

Group	Intervention	Description
digital denture conversion	digital denture conversion	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.
conventional denture conversion	conventional denture conversion	a conventional denture conversion will be done following the conventional fabrication technique.

Primary Outcome Measures

Name	Time	Method
Patient general satisfaction questionnaire	through study completion within 6 months	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.

Secondary Outcome Measures

Name	Time	Method
chair side working time questionnaire	through study completion within 6 months	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.
esthetic satisfaction questionnaire	through study completion within 6 months	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.
