The cortical screws for the transmandibular implant systems are available in lengths of 5,8,11,14 mm. Protocol is for the cortical screws to extending beyond the bone for a length of 2mm. This allows for tenting of the periosteum and thought to lead to subsequent bone growth.

Closed eruption technique: a crestal incision is made and a full thickness flap is reflected. Bone is carefully removed around the crown and a bracket attached. The flap is closed and the tooth is allowed to erupt down though the crestal incision site as traction is placed on the ligature. Apically repositioned flap had more

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
Topical application of local anesthetic agent can be accomplished orally (as a swish and swallow) or by transtracheal deposition into the tracheal lumen. However, these techniques may blunt the glottic and cough reflex, increasing the patient’s susceptibility to aspiration. The gag reflex can be further controlled by supplementary nerve blocks to the lingual branch of

Patients who have had a laryngospasm may be susceptible to secondary pulmonary edema. This can be the result of negative alveolar pressure of an expanding diaphragm against a closed glottis, or due to barotrauma from positive pressure ventilation. Pulmonary trauma arising from laryngospasm may become clinically evident hours after the spasm. In this case, signs
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;
