Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
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.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
guided trephination-based protocol
The drilling process will be performed by guided trephination protocol.
* An appropriate trephine drill (Helmut Zepf Medizintechnik GmbH, Germany) will be used to create an initial osteotomy.
* The guide will be removed, and the depth and angulation of this initial osteotomy will be evaluated.
* The final drill of the chosen implant system will be used to complete the osteotomy.
* The implant (NeoBiotech Implant System, Neobiotech Co. Ltd. Korea) then will be placed freehand in a conventional manner.
guided 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
guided conventional drilling-based protocol
The drilling process will be performed by a guided conventional drilling protocol.
* Drilling (Neo NaviGuide System - Neobiotech Co. Ltd. Korea) will be performed throughout the guiding sleeve from the first drill to the final drill.
* The guide will be removed.
* The implant (NeoBiotech Implant System, Neobiotech Co. Ltd. Korea) then will be placed freehand in a conventional manner.
guided 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
