Vertical bone height may be a consideration in the treatment planning phase of simultaneous sinus lifting and implant placement. In general 4 mm of vertical bone height will provide a situation that may allow for simultaneous placement however, the true determinate is primary implant stability.

Peri-implantitis is defined as radiographically detectable peri-implant bone loss occurring after initial successful osseointegration combined with soft tissue inflammation lesion that demonstrates suppuration and probing depths of 6mms or more. The process begins at the coronal aspect of the implant, whereas the more apical portion remains clinically stable (osseointegrated).
The transfixion and hemitransfixion incision provide access to the caudal septum in endonasal rhinoplasty. The complete transfixion incision separates the medial crura from the septum. The hemitransfixion incision is only made on one side, and usually stops short of the anterior nasal spine, preserving tip support. The nasal dorsum is not approached with the transfixion
25% – closed primarily 25-50% – local tissue advancement >50% – flap or skin graft which replaces both the anterior and posterior lamella Manage 40% avulsion of upper eyelid o Full thickness skin graft from opposite upper lid is preferred due to similar skin thickness, color, texture and availability with minimal donor site morbidity.

During closure, adequate repair of the mentalis muscles is critical in order to avoid a “witches chin” deformity.
TMJ Degeneration: Molecular Mechanisms and Clinical Implications Degenerative disease of the temporomandibular joint (TMJ) is a complex, multifactorial process involving mechanical overload, inflammation, and biochemical degradation of joint tissues. At the molecular level, enzymatic breakdown of extracellular matrix components and cytokine-mediated inflammation play central roles in the progression of TMJ degeneration. Understanding these mechanisms is
The Steiner analysis is a cephalometric analysis useful in evaluating the degree of maxillary and mandibular incisor protrusion relative to the surrounding skeletal structures. The position of the maxillary and mandibular incisors is related to Nasion-A point (N-A) and Nasion-B point (N-B) lines using both angular and linear measurements.

Dermal Grafts in TMJ Discectomy: Clinical Outcomes and Limitations The use of dermal interpositional grafts following temporomandibular joint (TMJ) discectomy has been proposed as a method to improve joint function, reduce pain, and prevent degenerative changes after disc removal. However, current clinical evidence suggests that dermal graft placement offers limited advantages over discectomy alone. Understanding
Cartilagenous lacerations should be approximated to reconstruct anatomy and prevent chronic chondritic inflammation. Interrupted sutures may promote cartilage margin overlap; the use of figure of eight sutures prevents overlap of lacerated cartilage margins. Cartilage has a limited vascurlar supply, originating from overlying soft tissue; therfore extensive debridement of overlying soft tissue should be discourage. If

Karapandzic Flap In most instances of reconstructing one-half to two-thirds of the lower lip, the Karapandzic flap provides a good functional and esthetic result. The Karapandzic flap re-approximates the orbicularis oris muscle providing for adequate sphincter function of the lips. In addition, since the sensory and motor nerves are preserved, the flap allows for a
