Intraoral welding of implants-known since decades- conveyed to practice
In cases of complete oral rehabilitation there are multitudes of complications which may occur with either the surgical or prosthetic phase of implant dentistry. In order to mend this, intraoral welding technique has been introduced as a rescue.
In cases of deficient bone or atrophic ridges, higher chances of implant failure occur due to micromotion of implants during healing phase.
This is one phase procedure to attain the goal of primary stabilization of implants while fabricating immediate prosthesis to the patient on the same day of the surgery or within a few days.
Discussing about the advantages of welding, it rigidly splints the implants, helps in healing, distributes the force to all implants, and increases the success through Osseo integration of implants. In cases of implant overdenture, absolute stabilization of implants can lead to immediate loading and oral rehabilitation on the same day of surgery.
The welding of the implant abutments with titanium bars is done directly in the mouth. It also has an advantage of eliminating the possible errors or distortions due to the impression.
The rigid splinting of the implant abutments done before the immediate loading provides retention to the implants & decreases the stress exerted on the implants. The method incorporates either welding a titanium bar or a wire to the abutments of these implants. Once the implants have achieved the stability and retention, they can be loaded with crowns/ bridges or over dentures.
This has been reported leading to lesser degree of implant fractures. This means ensuring success for the longevity of the implants, in a short period of time. For example in a case of complete rehabilitation of a patient required extractions are done followed by insertion of implants (either 6 or more if required) into the jaw bones.
During the surgical stage the curettage of the gums is done simultaneously. The bite of the jaws is recorded at first before commencing any procedure.post implant insertion the intra oral welding of the abutments is done. Afterwards the fabrication of the hybrid denture prosthesis is done and fixed in the mouth.
The stabilized prosthesis helps in chewing & speech of the patients along with the natural aesthetic look. The discomfort due to the movement and clicking of the dentures is avoided in such cases. The aim of this new technique is to find the optimal conditions for the success of the implants through continuous joint without alterations in the intraoral welding of titanium by electric resistance technique.
The proposed technique allows intraoral welding of titanium for solidarization of dental implants to improving their primary stability. Commercially pure titanium (c.p. Ti) wires and dental screws were welded by electric resistance technique. Worldwide, clinical cases have demonstrated the effectiveness of this technique in the improvement of dental implants primary stability practically.
