Physiologic permanent retention following space closure.

Clinical orthodontists recognize that mechanical treatment of excessive space represents a minimum technical challenge. However, retention of this space closure may represent a major challenge to the clinician. With the introduction of direct-bond materials, the patient may benefit from a conservative, noninvasive, fixed retainer. The design described in this article features two main advantages: physiologic action and maximum cleansibility.

A temporary space maintainer using acrylic resin teeth and a composite resin.

A one-session technique for preparing a temporary space maintainer has been described. The technique consists of attaching an acrylic resin pontic to etched surfaces of natural adjacent teeth by means of a composite resin. The main advantages of this technique are elimination of premature tooth preparation, good esthetics, fair strength, low cost, and rapid completion of the restoration without the need of a dental laboratory.

Temporary space maintainers retained with composite resin. Part II: Fracture load in vitro.

The average fracture load during occlusal loading of pontics which were bonded to natural abutment teeth in vitro was found to be 56.1, 57.5 and 74.2 kg for natural, acrylic resin, and Restodent pontics, respectively. Coating the roots of the abutment teeth with a thin layer of silicone rubber before embedding them in stone slightly reduced the strength of the fixed partial dentures. Thermocycling the specimens with coated roots caused a considerable decrease in strength to fracture loads of 33.0, 17.9, and 37.3 kg for natural, acrylic resin, and Restodent pontics, respectively. Fracture of the enamel of natural tooth pontics was observed in a few specimens. The superior strength of the fixed partial dentures with natural tooth and Restodent pontics would indicate that these pontics are superior for clinical trials rather than acrylic resin pontics.

Rescue of a "hopeless" second premolar.

We present a case of a young male who was referred to our clinic because of a deep caries on the first lower left molar. The patient refused conservative treatment, and the caries progressed. After 2 years the first lower left molar had to be extracted. During standard x-ray procedures, a deeply impacted second lower left premolar was diagnosed. The boy was followed by our staff, and surgery was performed at proper time to enable eruption of the second lower left premolar. Orthodontic treatment allowed us to bring the element in a suitable position to place a provisional Maryland bridge. At a later stage the missing element (first lower left molar) will be replaced by an osteointegrated implant.

The clinical management of ectopically erupting first permanent molars.

The literature on ectopically erupting first permanent molars is reviewed. The progression of the ectopic condition is discussed along with factors that will affect the practitioner's decision on a mode of treatment. The optimal treatment approach depends on the clinical eruption status of /6/, the change in position of /6/, the amount of enamel ledge of /E/ entrapping /6/, the mobility of /E/, and the presence of pain or infection. A variety of treatment approaches together with diagnostic rationale and clinical guidelines are presented. Overall aspects of the malocclusion must be considered when planning the management of ectopically erupting first permanent molars.
