Influence of occlusal interferences on the periodontium in patients treated with fixed prosthesis.

Gingival bleeding, pocket depth, and tooth mobility were recorded, and occlusal analyses were made on 147 subjects treated with fixed prostheses placed 4 years earlier. The percent of gingival bleeding was greater in teeth with interferences than in those without interferences. A slight increase in pocket depth was found in connection with interferences. However, the difference was statistically significant only in the group with no preprosthetic treatment. No differences in tooth mobility were found between teeth with and those without interferences, possibly partly because of the splinting influence of the fixed partial dentures on the mobile teeth.

Reversal of obstructive sleep apnoea by continuous positive airway pressure applied through the nares.

Five patients with severe obstructive sleep apnoea were treated with continuous positive airway pressure (CPAP) applied via a comfortable nose mask through the nares. Low levels of pressure (range 4.5-10 cm H2O) completely prevented upper airway occlusion during sleep in each patient and allowed an entire night of uninterrupted sleep. Continuous positive airway pressure applied in this manner provides a pneumatic splint for the nasopharyngeal airway and is a safe, simple treatment for the obstructive sleep apnoea syndrome.

The stabilization of midface-fractures in the vertical dimension.

A frontal or zygomatic-bone wire-suspension is often insufficient to retain and stabilize the upper jaw after fractures of the Le Fort II or III type. Caudal and dorsal displacement of the maxilla can only be avoided by the use of intermaxillary immobilization in good occlusion. The use of a maxillary stabilizer makes long-term intermaxillary immobilization unnecessary. The displacement of the maxilla, which can often be observed during splinting and fixation with wire-suspension following midface fractures, can be avoided by the use of stable steel rods.

[Prosthetic reconstruction of the secondary deformed maxillary arch in a patient with congenital cleft].

A case history of a bilateral cleft lip and palate male patient is presented. He was operated late at the age of his twelve, without any previous orthodontic treatment. Surgical reconstruction included, lip, hard and soft palate, removal of the premaxilla, and later on the pharingoplasty. At the age of twenty years he was prosthetically rehabilitated. Nine inner telescope crowns were made in "Palador" silver alloy, and nine outer in chrom-cobalt splinted together and connected with the skeletal frame. Intermaxillary relations were recorded and established in a manner used in the construction of complete dentures, and occlusion of the teeth, too. A complete obturation of the oronasal communication in the palatomaxillary section was achieved. The patient was followed up throughout next twenty years.

[Temporomandibular joint an insufficient dentition].

The disease of the orofacial organ is predominantly a dysfunction, the parts of the organ affecting one another reciprocally. All changes in the dentition disturb the balance and may produce occlusal disorders. For this reason, it is recommendable to initiate the prosthetic treatment of the incomplete dentition as early and properly as possible. Temporary biteguard splints (fig. 3) have proved a success.

Medical palatine cyst and maxillary antral osteoma: report of an unusal case.

A case is presented of a patient with the coincidental occurrence of two unusual lesions, median palatine cyst and osteoma of the maxillary antrum. There was no atypia of either lesion, but this combination led to the impression that the median palatine cyst had eroded into the maxillary antrum. Both lesions are usually asymptomatic and were incidental findings in this case. An occlusal radiograph is best for showing the palatal radiolucent area and is usually diagnostic. The preferred treatment for median palatine cyst is enucleation; a palatal splint is an excellent aid for reapproximation of the mucoperiosteal flap. The maxillary antrum was explored to obtain a biopsy specimen for a microscopic diagnosis of the radiopaque lesion; this proved to be an osteoma. The diagnosis of an osteoma is an indication for a radiographic survey to rule out Gardner syndrome, which has serious implications.

Dental treatment of temporomandibular disorders and masticatory muscle pain.

The treatment of masticatory muscle and temporomandibular joint pain constitutes an important area in dentistry. Current information supports the use of reversible treatments for these disorders. Several recent references are discussed in relation to reversible treatment, the role of occlusion, and appliance therapy for internal derangement.

Immediate and early function of Brånemark System implants placed in the esthetic zone: a 1-year prospective clinical multicenter study.

BACKGROUND: Immediate/early implant function means great benefits for patients and therapists because treatment time and cost can be substantially reduced. This concept has become an accepted alternative for complete arch fixed restorations in the mandible, and clinical documentation is emerging for other indications. PURPOSE: The purpose of this prospective clinical multicenter study was to evaluate the outcome of implants placed in incisor, canine, and premolar regions in maxillas or mandibles. Implants were loaded with provisional crowns and bridges on the same day or within a few days and were followed up for 1 year during function. MATERIALS AND METHODS: Four centers treated 76 patients each in need of an implant-retained prosthesis in the anterior and premolar regions in the maxilla or mandible. A total of 116 titanium implants with machined surfaces (Brånemark System , Nobel Biocare AB, Gothenburg, Sweden) were placed: 74 in maxillas and 42 in mandibles. Eighty-seven prostheses were made, of which 63 were single crowns and 24 were bridges (supported by 53 splinted implants). Twenty-two implants in 14 patients were placed in fresh extraction sites. The goal with the preparation and insertion technique was to achieve good primary implant stability and a minimum implant insertion torque of 30 Ncm before the implant was completely seated. The occlusion was adjusted to eliminate direct contact with the provisional prostheses. After 6 months, the patients received their permanent prostheses. Sixty-seven patients were followed for 1 year. RESULTS: Five implants were lost in five patients, three in the maxilla and two in the mandible. Four of the lost implants were single-tooth replacements and one was splinted. The cumulative survival rate (CSR) was 95.7% for all implants after 1 year and 93.7% and 98.1% for single-tooth and splinted implants, respectively. There were no implant losses in the extraction sites. CONCLUSIONS: The CSR of 96% at 1 year indicates that immediate function of Brånemark System implants placed in incisor to premolar regions in both jaws is a viable concept. More failures occurred with single-tooth replacements (6.3%) than with splinted implants (1.9%).

The effect of a deprogrammer on the position of the terminal transverse horizontal axis of the mandible.

This study measured the amount of positional change in the terminal transverse horizontal axis of the mandible that results from altering undesirable neuromuscular influence. Centric relation records were made on 19 healthy subjects before and after deprogramming. The axis was located with a computerized axiograph, and the centric relation records were compared in vivo at the axis location. The positional change of the axis was quantified in three dimensions at an accuracy of +/- 0.05 mm. The net amount of positional change was compared to scores from the temporomandibular joint scale to test for correlation with the potential for developing a temporomandibular disorder. The findings showed that the amount of positional change in the terminal transverse horizontal axis in 18 of 19 healthy patients after 12 hours of deprogramming was less than 0.5 mm and did not correlate with scores from the TMJ Scale.

Maintenance of condyle-proximal segment position in orthognathic surgery.

Twenty patients underwent bilateral sagittal ramus osteotomy for the correction of mandibular retrognathia. A condylar positioning device (CPD) was used intraoperatively in 10 patients to maintain preoperative condyle-proximal segment position, while the CPD was not used in the other 10 patients. Postoperatively, the condyle-proximal segment positions in both groups were compared and evaluated for vertical, horizontal, and rotational changes. A significant improvement (P less than .05) was observed in the vertical and horizontal condylar position in the group in which the CPD was used. However, there was no significant difference in proximal segment rotation.

Internal derangement of the TMJ: changes associated with mandibular repositioning and orthodontic therapy.

Because of its apparent success in relieving symptoms, especially pain, anterior mandibular repositioning therapy is a popular mode of nonsurgical treatment for patients with painful, clicking internal derangement of the temporomandibular joint. Posterior open bites are a frequent consequence of such therapy and may necessitate either continued appliance wear or closure by equilibration, prosthetics, or orthodontics. The anatomic and functional changes that occur subsequent to mandibular repositioning during orthodontic closure of the posterior open bite are not well understood. A case of a patient with a Class II, deep bite malocclusion and painful internal derangement of the TMJ is presented. Transcranial and cephalometric radiographs, arthrograms, and mandibular movement recordings were obtained before treatment and after both repositioning therapy and orthodontic treatment. Regarding occlusal improvement and pain relief, the treatment was successful. However, not all of the changes that occurred during repositioning therapy were maintained after orthodontic treatment. The strategy used in this case (mandibular repositioning/orthodontic finishing) was evaluated by an examination of these anatomic and functional changes with a discussion centered on the possible mechanisms involved.

[Treatment of burns in infants].

Because of the potential severity of their residual deformities, burn injuries in infants justify an early management in specialized centres when they cover more than 5% of body surface and in every case when hands, face, or external genitalia are concerned. Cooling with cold water is the first aid treatment to be performed as early as possible after the injury. The treatment in specialized centres must be both general and surgical. General treatment includes fluid and electrolyte therapy, temperature control, appropriate nutrition and pain suppression. Pain suppression is a major part of the treatment and morphine must be largely used. Surgical treatment starts as soon as the patient arrives in the centre and is eventually performed under general anesthesia: all the burned areas are covered with occlusive dressings. Infections are prevented by systematic cultures and adjusted antibiotic therapy. A vigorous rehabilitation program must be instituted as soon as possible: massages, compressive clothes, splints, physical therapy, plastic surgery. Primary prevention by sustained parental education is important in order to reduce the frequency of burn injuries in infants.

Radiographic investigations into temporomandibular joint function.

A three-phase investigation was conducted to learn more about the suspension mechanism of the temporomandibular joint with the aid of radiographs. Results indicate that superior condylar displacement occurs in most patients with unsupported closing muscle force and that condylar translation occurs during hinge opening for some patients. This study revealed that the condylar mechanism is not immutable. The superior condylar displacement produced by unsupported muscle force raises doubts about the whole understanding of the suspension mechanism of the temporomandibular joint and the clinical techniques associated with it.
