After making the surgical treatment plan, the surgical movements are duplicated in the model surgery. During this procedure, reference points and lines are drawn on the base of the models over the dental arch, and sawcuts are made according to these marked osteotomy lines. This method requires more accuracy for better postsurgical results in that the surgical splint which enables the surgeon to position the jaws intraoperatively is made from the casts as repositioned by the model surgery, and finally it will define the postsurgical results. This technique, however, has been found to be inexact, especially when the jaws are moved in several dimensions simultaneously. To overcome this, different methods have been developed for an accurate repositioning of the jaws as planned. A new appliance, Surgical Jaw Relator, was devised by the author for the simple 3-dimensional relocation of the upper and lower models, resulting in the easy construction of the splints such as centric relation splint, intermediate and final splint. This article describes an introduction and a clinical application of this appliance.

If there are problems for us to sleep, we are faced with fatigue and dizziness in the day. Snoring and OSAS (obstructive sleep apnea syndrome) during sleeping are the main cause of sleep disorder. Treatments through surgical method and sleep splint can be performed to treat snoring and OSAS. Relapse of snoring and OSAS is common after treatment by surgical method. But, Recently sleep splint is frequently applied to treat snoring and OSAS with surgical treatment, because it is convenient and conservative. Sleep splint treat snoring and OSAS by ensuring airway through nose. As first step of fabrication occlusal bite is gained at a point that patient get feeling of increased nasal breathing in supined position, and next, the bite is transfered to sleep splint. This study surveyed the effect of sleep splint by questionnaire to the out-patients (the Dept. of Oral and Maxillofacial Surgery, Chonbuk National University Hospital) weared sleep splint and their partners, secondarily measured airflow through nose by aerophone II after wearing sleep splint and finally evaluated the effect of treatment of snoring and OSAS by sleep splint. The obtained result were as follows; 1. Though 'sleep splint' couldn't eliminate fundamental problems of snoring, it could improve the symptoms when patients were selected could using the 'Nakagawa's respiration method'. 2. Patients who used the sleep splint could breathe stably when patients are sleeping stably. Wearing a 'sleep splint' improved airflow by expanding the upper airway. 3. Even though sleep splint can be made with variable materials, the patients expressed the most satisfaction on the splint with '0.75mm hard shell'. 4. The 'Herbst' may allows the mandible to move the TMJ to relax. Nevertheless, some patients experienced a discomfort or irritation. 5. In Snoring and OSAS cases, it is recommended that patients should first explore non-surgical options prior to choosing a surgical treatment.

Hemophilia is a hereditary condition in which one of the normal blood clotting factors is absent. This sex-linked, recessive disease, transmitted by the female and expressed in some of her male offspring, is characterized by significantly delayed coagulation times and by the tendency to hemorrhage. On the dental treatment especially, surgical procedure, appropriate methods of hemorrhage control are required. These methods are replacement therapy, antifibrinolytic agents, and local hemostatic methods. In this case, we successfully extract residual roots of hemophiliac patient without eccessive post operative bleeding using replacement therapy and surgical splint.

Temporomandibular joint (TMJ) dislocation is defined that the disc-condyle complex is positioned anterior to the articular eminence in the open mouth position, and is unable to return to a normal closed mouth position without a manipulative maneuver. TMJ dislocation can recur habitually and result several problems to patients such as discomfort, pain, fear, and anxiety. The only definitive treatment for TMJ dislocation is surgical alteration of the joint itself. In most cases, however, a surgical procedure is far too aggressive for the symptoms experienced by the patient. In addition, the effect of surgical treatment may be insufficient, and the recurrence have been reported. It is also possible to develop several complications after surgical treatment. Therefore much effort should be directed at supportive therapy in an attempt to eliminate the disorder or at least reduce the symptom to tolerable levels. Through this cases the authors present favorable treatment outcome using occlusal splint with the patient of TMJ dislocation. Occlusal splint therapy can be considered as easy, safe, and useful non-invasive modality to treatment of TMJ dislocation.

The contemporary two-jaw surgical approach usually involves a Le Fort osteotomy of the maxilla and a ramal osteotomy of the mandible with 3-dimensional repositioning of the jaws as well as the occlusal planes. After making the surgical treatment plan. the surgical movements are duplicated in the model surgery. During this procedure, reference poings and lines are drawn on the base of the models over the dental arch and sawcuts are mads according to these marked osteotomy lines. This technique, however, has been found to be inexact. especially when the laws are moved in several dimensions simultaneously. To overcome this. different methods have been developed for an accurate repositioning of the jaws as planned. A new appliance. Surgical Jaw Relater, has been devised by th8 author for the simple 3-dimensional relocation of the upper and lower models, resulting in the easy construction of the splints such as centric relation splint, intermediate and final splint. This article describes an introduction and a clinical application of this appliance. Through the application of this system to the orthognathic cases including two-law surgery. it is proved that the row device is very clinically useful.

In general, treatment of the patients with closed lock divides into a conservative and a surgical treatment. Surgical treatment has been often applied in case that occlusal splint therapy was not effective on the patient with closed lock. In recent, some clinicians reported good results with mandibular manipulation. Three patients complained limitation of month opening-(mean mouth opening was 22.3mm) and TMJ pain. Articular discs were displaced anteriorly on MRI. Two patients didn't improve the symptoms with long term occlusal splint therapy. We applied mandibular manipulation after injection with 2% lidocaine into the upper joint space of the affected TMJ and directly inserted occlusal splint to all patients. At the follow-up check, mean mouth opening was 41.7mm. TMJ pain decreased, condyle and disc relationship was improved functionally on MRI.

Adequate positioning of the hand is a critical step in hand fracture operative repair that can impact both the clinical outcome and the efficiency of the operation. In this paper, we introduce the use of a thermoplastic splint with an added thumb stabilizing component as a means to increase the surgeon's autonomy and to streamline the patient care pathway. The thermoplastic splint is custom fabricated preoperatively by the specialist hand therapist. The splint is used prior, during, and post operation with minimal modification. The thumb component assists maintaining the forearm in a stable pronated position whilst drilling and affixing metal work. This is demonstrated in the video of removal of metal work and open reduction and internal fixation of a metacarpal fracture.

Snoring and obstructive sleep apnea (OSA) are common sleep disordered breathing conditions. Habitual snoring is caused by a vibration of soft tissue of upper airway while breath in sleeping, and obstructive sleep apnea is caused by the repeated obstructions of airflow for a sleeping, specially airflow of pharynx. Researchers have shown that snoring is the most important symptom connected with the obstructive sleep apnea syndrome The treatment is directed toward improving the air flow by various surgical and nonsurgical methods. The current surgical procedures used are uvulopalatopharyngoplasty(UPPP), orthognathic surgery, nasal cavity surgery. Among the nonsurgical methods there are nasal continuous positive air pressure(CPAP), pharmacologic therapy. weight loss in obese patient, oral appliance(sleep splint). Sleep splint brings the mandible forward in order to increase upper airway volume and prevents total upper airway collapse during sleep. However, the precise mechanism of action is not yet completely understood, especially aerodynamic factor. The aim of this study evaluated the effect of conservative treatment of snoring and OSAS by sleep splint through measured aerodynamic change by an aerophone II. We measured a airflow, sound pressure level, duration, mean power from overall airflow by aerophone II mask. The results indicated that on a positive correlation between a decrease in maximum airflow rate and a decrease in maximum sound pressure level, on a negative correlation between a decrease in maximum airflow rate and a increase in duration.

A 7-year-old intact female Maltese dog presented with a history of bite wounds. Physical examination revealed labored breathing, four puncture wounds with subcutaneous emphysema of the thorax, and paradoxical respiratory movement of the right thoracic wall. On radiography, a segmental fracture of the right 7th rib and a single fracture of the 8th rib were evident on the dorsal thorax. An inward displacement of the fractured segment and contusion of the right caudal lung lobe were identified with computed tomography. A diagnosis of pseudo-flail chest was made. Exploratory thoracotomy revealed a full-thickness muscular defect, a marked discoloration of the right caudal lung lobe, a segmental fracture of the right 7th rib, and a single fracture of the right 8th rib. Necrotic tissues were removed using surgical debridement. The fractured 7th and 8th ribs were corrected using a single interfragmentary wiring technique. The thoracic wall was reconstructed using the latissimus dorsi muscle flap. Additional thoracic stabilization using a thermoplastic splint was applied to correct paradoxical respiratory movement. The external splint was removed 4 weeks postoperatively. There was no evidence of respiratory abnormalities 18 months postoperatively.

Le fort 1 osteotomy surgery is one of the most popular surgical methods for the treatment of patients with facial bone deformities. An intermediate wafer splint is used to fix the bone segment to the planned position, but there are many steps that can cause errors. To reduce these errors, we propose a method of using a surgical guide made with virtual surgical simulation.
