About

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

Full 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.

Enrollment: 22 patients

Sex: All

Ages: 20 to 50 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

1. Single missing maxillary premolar or molar tooth.
2. Both genders aged from 20-50 years.

5. Bone width in bucco-lingual direction ≥ 6 mm.
6. Uniform alveolar ridge with no undercuts.
7. Present mesial and distal sound neighboring teeth.
8. At least 4 natural remaining teeth on the same arch.
9. Mouth opening at least 30 mm.

guided trephination-based protocol

Experimental group

Description:

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.

Treatment:

Procedure: guided trephination-based drilling protocol

guided conventional drilling-based protocol

Active Comparator group

Description:

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.
