- Missing tooth on #31

- Implant supported single crown on #31 and #42
- Endodontic treatment on #41
- Crowns on #32 and #41
C26_Anterior_02
Site #31 following the old bridge removal seemed to have enough bone and soft tissue.

C26_Anterior_03
Extraction socket #42 and bone defect on the buccal side of #31.

C26_Anterior_04
Site #31 was drilled using a Ф1.5mm drill in the S-mini kit. The labial side was exposed and in need of bone graft.

C26_Anterior_05
A Φ2x11.5mm S-mini onebody implant was being placed.

C26_Anterior_06
35Ncm of insertion torque was achieved.

C26_Anterior_07
An allograft material (RegenOss) was packed on the labial defect, then a collagen membrane was placed over the graft. A Φ2.5mm S-mini implant was placed in the socket #42 with flapless surgery and graft.

C26_Anterior_08
The graft area was secured with sutures.

C26_Anterior_09
Additional bone materials were inserted into the defect.

C26_Anterior_10
Radiograph taken after the surgery.

C26_Anterior_11
The implant was immediately loaded with an acrylic resin provisional restoration.

C26_Anterior_12
The final impression was taken using impression caps # weeks after the surgery. By using an impression cap, a shape of subgingival post can be taken without gingicord insertion.

An impression taken with impression caps.

C26_Anterior_15
2 modified lab analogs were repositioned by placing them in the stone poured analog bed.

C26_Anterior_16
Original analogs (left) and modified analogs (right).

C26_Anterior_17
Modified ones are applicable on impression with slight resistance.

C26_Anterior_18
Stone dies fabricated with stone abutments.

C26_Anterior_20
The final restoration delivered 4 months after the surgery.

C26_Anterior_21
Radiological 4 months follow-up.

C26_Anterior_22
Facial view of the patient's smile 3 months after the surgery.

C26_Anterior_23
3 years follow-up. No further bone loss was found.

C26_Anterior_24
Clinical view of four mandibular anterior teeth.

Esthetic embrasure is hard to get in the mandibular anterior region with a 2-staged implant (top). This case shows surgical to prosthetic procedures of onebody implant placement and immediate loading on #31 and #42 (bottom).
