Esthetic Outcomes Following Immediate Implant Combine With Soft Tissue Augmentation

Inclusion Criteria:

- patients who are in need of a tooth extraction at the maxillary premolar, canine and
incisor region, and subsequent single implant placement.

- The reasons for extraction will include poor endodontic prognosis and/or unrestorable
teeth (extensive caries, traumatic fractures, fractures of endodontically treated
teeth, root perforation, root resorption with or without radiographic periapical
lesion up to 3 mm in diameter). patients who are systemically healthy or with
controlled common systemic conditions (controlled hypertension, controlled diabetes
HbA1c up to 7 %).

- adjacent teeth have to be present and the eligible tooth has esthetically acceptable
buccal gingival margin position prior to surgery, compared to neighboring teeth and
contralateral tooth, and adequate width of buccal keratinized gingiva(≥3mm).

- level of radiographic bone level has the distance from CEJ to interproximal crest up
to 4 mm.

- Location of buccal alveolar crest has to be generally within 4 mm from the free
gingival margin, verified after the extraction, before randomization; and
fenestration, if present, up to 3mm in diameter at the apical part of the root and
affecting less than 30% of the buccal socket wall.

Exclusion Criteria:

- currently smoke exceeding 10 cigarettes/ day

- severe parafunctional habits, malocclusion or intent of orthodontic therapy in the
future and are pregnant.

- teeth in the surgical site will be excluded if there is advanced periodontal disease
or periapical lesion causing significant bony defects that are beyond the criteria
mentioned at Section 3.3.

- allergy to antibiotics contained in the ADM (Gentimicin, Cefoxitin, Lincomcin,
polymixin B and Vancomycin) will not be included in the immediate implant combined
with ADM group.
