Connect implants and natural teeth with bridge?
I have seen a number of cases where implants and natural teeth are connected by a bridge. I know traditionally this was not considered a viable long-term option. One of the problems noted in the past was that the natural abutment teeth intruded creating gaps at the crown margins. But with more and more cases like this being done, and apparently many surviving, what is the current thinking? Any contraindications? Any special or new techniques?

The tooth will move more than the implant. In posterior areas where the teeth are not clinically mobile and the span is short with the use of permanent cement and retentive preparation of the tooth there is not likely to be a problem. The implant should never be center between two natural teeth as the teeth will be moved in a vertical direction and rock on the implant resulting in lateral rather than vertical forces on the implant. Also the more to the anterior that the implant is, the greater the lateral load on the teeth and on the implant and the greater the risk of failure. Stress breaker connections for implant to teeth also work well.

it is gambling.
some outliers may survive. But generally not ok.
and there is not any new thought about connecting implant and teeth.

Abfraction
From Wikipedia, the free encyclopedia
Clinical presentation of abfraction non-carious tooth tissue lesions on the cervical margins of upper left canine and premolar
Abfraction is a theoretical concept explaining a loss of tooth structure not caused by tooth decay (non-carious cervical lesions). It is suggested that these lesions are caused by forces placed on the teeth during biting, eating, chewing and grinding; the enamel, especially at the cementoenamel junction (CEJ), undergoes large amounts of stress, causing micro fractures and tooth tissue loss
