A thick biotype provides greater stability for the peri-implant soft tissues with more predictable healing response following surgery and around restorations. Thin bioptypes predispose to unpredibtable healing and allow titanium show through. Dennis Tarnow demonstrated that a distance of 6mm or more from the alveolar crest to contact point reduces the probability of intact papillae. […]

Cricothyroidotomy is not recommended in children less than 12 years of age, since the cricoid cartilage is the only circumferential support to the upper trachea.
Cluster headaches have a much higher incidence in men than women. The pain is often retro- orbital and is described as intense and boring in character. In addition to the above symptoms, there may be miosis, ptosis, flush and cheek edema which may last for two hours. It recurs nightly for weeks to months followed
TMJ arthrocentesis is based on the hydraulic pressure created by a lavage solution to remove inflammatory mediators and degradation products present in the synovial fluid, decrease the negative pressure within the joint, and break intra-articular adhesions formed between the mandibular fossa and the articular disc Tragal-lateral canthus line (Holmlund-Hellsing line) is a line from the
Arthrokinetic Reflex: Definition, Mechanism, and Clinical Relevance The arthrokinetic reflex is an important orthopedic and neuromuscular concept that explains the relationship between joint mechanics and muscle activity. In the context of temporomandibular joint (TMJ) disorders, this reflex helps explain why internal derangement of the joint can lead to muscle spasm, pain, and dysfunction—and why these

Free soft tissue graft is not vascularized 1-3 days: plasmatic imbibition 2-3 days: inosculation Unlike flaps, grafts are dependent on nutrition from the recipient bed (plasmatic circulation or imbibition) for 48-72 hours; beyond that, neovascularization and inosculation take over Split thickness skin graft: include the epidermis and portion of dermis; usually 0.3-0.45mm (0.012-0.015in) thick;

Releasing incisions aid in providing visualization and surgical exposure. A vertical releasing incision should cross the free gingival margin at the line angle of the tooth and should not be directly on the facial aspect of the tooth nor directly in the papilla. The incision is not a straight vertical incision but rather oblique, to
Condylotomy has been shown to work most favorably in cases of anterior disc displacement, especially in the setting of disc displacement with reduction. Modified condylotomy can effect disc reduction and alter favorably the natural course of internal derangement in reducing disc displacement A posteriorly directed osteotomy is more likely to be associated with excessive condylar

Hemifacial microsomia is associated with several soft tissue anomalies in addition to the common skeletal manifestations. These include, but are not limited to, microtia, facial nerve palsy, skin tags, soft tissue and muscular hypoplasia, microphthalmos, and macrostomia. The facial deformities associated with hemifacial microsomia are heterogeneous and demonstrate extreme variability of expression. Previous work by

Article: Cleft Palate Repair and Its Variations In contrast to cleft lip and palate, there is a female predominance of cleft palate. The ratio is approximately 3:2. Passavant’s ridge is a soft tissue prominence which extends into the pharynx. The structure is usually described in association with cleft palate, but has been described in many
