The literature in the peer-reviewed journals seems divided on the question of connecting dental implants to natural teeth in fixed partial dentures. The problem encountered is the submersion of natural teeth producing a gap between the fixed partial denture crown margin and the prepared tooth. Some literature supports the position that dental implants and natural teeth should not be connected. Some literature supports the position that dental implants and natural teeth can be connected with rigid attachments (solid metal framework, solder joint) but not with non-rigid attachments (precision attachments).

Implant to Natural Tooth Splinting
Doctors who use this philosophy will sometimes connect an implant to a natural tooth. The advantage of this is that by connecting implants to natural teeth, fewer implants are needed to complete the case. This can dramatically reduce the cost of treatment while allowing the patient to have permanent teeth. The disadvantage of this type of treatment is that should a problem arise with either the implant or natural tooth the problem has to be handled differently because the implants and natural teeth are connected. Furthermore, there are limited data regarding the effects of splinting implants to natural teeth. In this regard, it has been reported that intrusion of splinted teeth and pronounced vertical bone loss around implant abutments are potential sequelae;however, the majority of patients, , in one study suffered no adverse effects. Other reports have indicated that connecting implants to teeth in a fixed prosthesis has a good prognosis. A 5-year prospective study designed to compare bridges supported only by implants with bridges supported by both implan.1.jpg)
ts and natural teeth within the same patient, noted no higher risk of implant or prosthetic failure for tooth-implant fixed bridges as comparedwith implant-supported bridges.

In general,the implants not connected with natural teeth is best choice.
ReplyDeleteThere are small percentage of natural teeth intrusion when inplants connected with natural teeth.(<5%)
For the safe pointview, seperate the implants and teeth.
If you must to splint implants with teeth, you should put a rigid connector(like T-block or rigid screw...)into the connection between implants and teeth.
Or, put on the inner crown with rigid cement and outer crown with weak cement.
