Immediately Loaded Intraorally Welded Complete-Arch Maxillary Provisional Prosthesis.

Area of Science:

• Dentistry
• Oral Surgery
• Biomaterials

Background:

• Computer-guided implant surgery (CGIS) utilizes stereolithographic guides for precise implant placement.
• Immediate loading of dental implants with prefabricated prostheses can present challenges in achieving passive fit.
• Flapless surgical techniques combined with CGIS and immediate loading are associated with frequent complications.

Observation:

• Achieving a passive fit for prefabricated prostheses on implants placed on the same day is often difficult.
• Existing methods for guided implant surgery and immediate prosthesis loading have limitations in accuracy and complication rates.
• The accuracy of stereolithographic surgical guides in CGIS is not absolute.

Findings:

• A new treatment approach is proposed for immediate implant loading using CGIS.
• This approach involves an intraoral welded full-arch provisional prosthesis.
• The novel method aims to overcome the difficulties in achieving passive fit for immediately loaded prostheses.

Implications:

• This technique may enhance the predictability and success of immediately loaded implants placed via CGIS.
• It offers a potential solution for improving prosthesis fit and reducing complications in full-arch reconstructions.
• Further clinical evaluation is warranted to validate the efficacy of this intraoral welding technique.
