Brief summary

This study will be initiated to compare the accuracy of implant placement using the guided trephination drilling protocol and the guided conventional drilling protocol.

Detailed description

This study will be conducted to compare the accuracy of implant placement using the guided trephination drilling protocol and the guided conventional drilling protocol. the patients with a single missing tooth will be assigned to one group ( trephination drilling / conventional drilling ).the preoperative virtual planning and fabrication of a surgical guide will be made for each patient. after implant placement according to each group, postoperative (CBCT ) will be performed to compare the virtual implant position and the actual implant position.

Interventions

PROCEDUREguided trephination-based drilling protocol

the implant site preparation in this group will be done by guided trephination protocol which uses the surgical guide to trephine the implant site then remove the guide and continue the drilling in a freehand manner

PROCEDUREguided Conventional drilling-based protocol

the implant site preparation in this group will be done by a guided conventional drilling protocol which uses the surgical guide to guide the sequential drills up to the final drill
