Brief Summary

First, participants will undergo clinical and radiographic examination for taking all the needed preoperative records, then endodontically treated teeth preparation starting with removal of any carious or undermined tooth structure then ferrule preparation then followed by intra-radicular preparation and then placement of the provisional restoration. In the third visit we will take the final impression of the post space for each patient by using the intraoral scan and extraoral scan o f the conventional impression. Then assessment of the apical gap length by using digital periapical radiograph using the paralleling technique and assessment of post adaptation using replica technique followed by placement and permanent cementation of the zirconia custom made post and core restoration that showed less apical gap length and better adaptation then taking the final impression for the extracoronal restoration and finally permanent cementation of the extra coronal fixed restoration.

Conditions

Endodontically Treated Teeth

Outcome Measures

Primary Outcomes (1)

• Apical gap length

  measuring apical gap length by the digital Periapical radiograph using the paralleling technique.

  through study completion, an average of 1 year".

Secondary Outcomes (1)

• Post adaptation

  through study completion, an average of 1 year".

Study Arms (2)

Direct intra-oral scanning technique for the post space.

EXPERIMENTAL

intervention will be the direct scanning of the prepared post space inside the patient mouth by using an intraoral scanner.

Other: Direct intra-oral scanning technique for the post space.

In-direct scanning of the conventional post space silicone impression.

ACTIVE COMPARATOR

The comparator will be extraoral scanning of the conventional sillicon impression of the prepared post space by using an extraoral scanner.

Other: Direct intra-oral scanning technique for the post space.
