Clinical Trial Summary
Due to the evolution of esthetic implant dentistry and tissue regeneration (hard and soft
tissue), flap design plays a crucial role in the maintenance and regeneration of the marginal
soft tissue and interdental papillae around dental implants. The present study aims to
compare soft and hard tissue changes following immediate implant placement with ridge
augmentation using the vestibular flap versus single flap approach.
Description:
Achieving and maintaining optimal esthetics around maxillary anterior single implants is a
demanding task. Despite the high success rates achieved with osseointegrated implants,
inevitable loss of soft and hard tissue following tooth extraction often results in
compromised vertical and horizontal dimensions of the peri-implant soft tissue in terms of
esthetics. Various surgical techniques have been advocated to overcome the expected alveolar
ridge dimensional changes in immediate implant placement, including the use of connective
tissue grafts, bone grafts, flapless implant placement protocol and the different flap
designs .
Different flap designs available include vestibular incision, papilla sparing, envelope,
triangular, and trapezoidal. Selection of the ideal flap design is case dependent, and is
based on several factors such as, smile line, gingival biotype, width of the edentulous area,
and the proposed treatment plan. It has also been reported that flapless implant placement is
a predictable procedure with a high success rate and less patient discomfort, minimizing the
overall procedure time, postoperative pain, and inflammation. However, flapless surgery has
been regarded as a technique with limitations regarding bone augmentation.
Therefore, cases with labial bone defects during immediate implant placement require flap
mobilization to achieve the needed coverage for ridge augmentation, despite of the proposed
drawbacks to flap reflection, such as the increased postoperative sequelae, recovery time,
and reduced blood supply after flap adaptation. A single flap approach, a modified form of
the envelope flap, has been suggested as an alternative to allow for ridge augmentation in
esthetic immediate implant cases with labial bone defects. Whereas the vestibular incision,
one horizontal full-thickness incision in the vestibule is considered a minimally invasive
aesthetic ridge augmentation technique away from the gingival margin and sulcus, intending to
maintain the volume and contour of the supra crestal soft tissue.
