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

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| guided trephination-based drilling protocol | Procedure | 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 |
| Measure | Description | Time Frame |
|---|---|---|
| Horizontal deviation at apex of the implant. | measure the Horizontal deviation at apex of the implant between the virtual planning position and the actual implant position | immediately after the intervention |
| •Horizontal deviation at implant shoulder. | measure the Horizontal deviation at the implant shoulder between the virtual planning position and the actual implant position | immediately after the intervention |
| Angular deviation. | measure the Angular deviation of the implant between the virtual planning position and the actual implant position | immediately after the intervention |
| Measure | Description | Time Frame |
|---|---|---|
| The duration of the surgery | measure the time of the surgery from the first drill to the implant placement | during the surgery |
| Satisfaction assessed by the Visual Analogue Scale | measure the patient satisfaction score on terms of pain and discomfort from 1 to 10 |
