Immediate fixed interim prostheses supported by two-stage threaded implants: methodology and results.

Area of Science:

• Dentistry
• Oral Implantology
• Prosthodontics

Background:

• Traditional implant restoration protocols require a lengthy healing period, often necessitating the use of temporary complete dentures.
• This extended healing phase can be particularly burdensome for patients, especially those with remaining natural teeth, leading to dissatisfaction.

Purpose of the Study:

• To present an alternative approach for mandibular fixed-detachable bridge reconstruction that bypasses the need for transitional removable prostheses.
• To evaluate the efficacy and long-term outcomes of this modified implant restoration technique.

Main Methods:

• Placement of Nobelpharma fixtures, with specific positioning related to foramina and the symphyseal region.
• Immediate connection of abutments to selected fixtures and conversion of a pre-existing mandibular denture into a fixed bridge.
• Conventional healing for the remaining implants.

Main Results:

• The technique was successfully applied in seven patients, allowing for immediate reconstruction with mandibular fixed-detachable bridges.
• Patients did not require the use of removable prostheses during the implant healing period.
• No adverse effects on the overall long-term implant therapy were observed.

Conclusions:

• This innovative method offers a viable alternative to conventional transitional removable prostheses for implant-supported fixed-detachable bridges.
• It significantly improves patient comfort and acceptance by eliminating the need for temporary dentures.
• The long-term success of implant therapy is not compromised by this accelerated restoration approach.
