Summary
Laser welding of dental prostheses allows for efficient, in-person repairs, reducing patient visits and lab work. This study confirms the feasibility and safety of intraoral laser welding for metal prostheses in human subjects.
Area of Science:
- Dentistry
- Biomaterials Science
- Laser Technology
Background:
- Traditional dental prosthesis repair often involves multiple patient visits and laboratory procedures.
- Previous research established the feasibility of in vitro intraoral welding using a neodymium:yttrium-aluminum-garnet (Nd:YAG) laser, assessing thermal variations.
- This study aimed to evaluate the efficacy and safety of intraoral laser welding in a clinical setting.
Observation:
- Intraoral welding was performed in vivo on human subjects using a fibre-delivered Nd:YAG laser.
- A restored prosthesis was successfully positioned and welded in the upper central sector.
- Patient comfort and aesthetic outcomes were assessed post-procedure.
Findings:
- The in vivo application of intraoral laser welding proved successful for metal dental prostheses.
- Optimal results were achieved regarding patient comfort and aesthetic integration.
- No significant problems or risks to adjacent biological structures were identified during the welding process.
Implications:
- Intraoral laser welding offers a streamlined approach to dental prosthesis repair, minimizing patient inconvenience.
- This technique enhances the potential for chairside adjustments and immediate prosthesis restoration.
- The findings support the clinical adoption of laser welding for improved dental prosthetic care.
