> Implant: Straumann Bone level Regular CrossFit SLActive
Fig. 18 Ten weeks after implant placement, spontaneous exposure of the healing cap was observed.
This was not an ideal occurrence, however the premature exposure of the healing abutment did not
result in significant recession of the soft tissues on
the facial site.
Fig. 19 The patient then returned to the prosthodontist, who constructed a provisional implant
restoration to begin modifying the transmucosal
emergence contour and to allow further maturation
of the soft tissues.

Fig. 20 Eight months after initial extraction and
grafting, the definitive implant prosthesis was delivered.
> Medication:
Antibiotic prophylaxis 3 g amoxicillin taken orally one hour before the surgical procedure, followed by 1.5 g amoxicillin daily in
3 divided doses for 5 days. Concurrently, twice daily rinsing with chlorhexidine digluconate (0.2 %)
> Biomaterials: Geistlich Bio-Oss® Collagen (100 mg), Geistlich Mucograft® Seal (8 mm diameter),
Geistlich Bio-Oss® 0.5 g (0.25 mm–1 mm), Geistlich Bio-Gide® 25 x 25 mm

the implant optimally integrated into the bone 2
years post-extraction or 18 months after commencement of restorative procedures.
Fig. 25 The long-term CBCT control shows an optimal facial wall of approximately 2 mm thickness
2 years post-extraction or 18 months after commencement of restorative procedures.
Fig. 26 An occlusal view 2 years after extraction,
shows a stable emergence profile and an aesthetic
result.
