TPS implants are made of pure titanium, and the surface is sprayed with titanium slurry. The implant was first proposed by Ledernann of Switzerland, and it is an immediate implant. It can be used for the restoration of a single missing tooth or for the auxiliary retention of the mandibular complete denture, but it is not recommended for the maxilla. TPS implantation often requires four implantation nails as brackets, plus bow rod connections. During the operation, a mechanical drill was used to drill a pilot hole in the alveolar bone, and the rest of the operations were done with manual tools.
After the implant is placed, the gingiva is directly inserted, and the tooth can be worn without waiting for the bone to heal. In 1988, Ledermann carried out the second modification of TPS. The main feature of the modification is to change the bone tissue joint of the implant to a sanded structure, and to increase the self-tapping performance of the implant, which can be directly grooved on the bone wall. Screw in to increase its stability.
