Are removable appliances obsolete?

Removable orthodontic appliances have some limitations compared to fixed appliances. However, a removable appliance can be used during each period of craniofacial growth and dental development. A number of clinical applications for the removable appliance during the mixed and permanent dentition is explained. The use of functional orthopedic appliances and removable retention appliances are also described. It is concluded that the removable appliance can still play a favorable part in the treatment of malocclusions in each developmental stage.

Patient cooperation in treatment with removable appliances: a model of patient noncompliance with treatment implications

The uncooperative or noncompliant patient presents a substantial problem during treatment with removable orthopedic/orthodontic appliances. Frequently, the uncooperative patient is labeled as having a poor or defiant attitude toward orthodontic treatment. In contrast to this attitude model of patient noncompliance, this article presents an analysis of uncooperative behavior in terms of behavior-environment relationships. The authors bring together backgrounds of expertise in both clinical psychology and orthodontics. The behavioral model presented is applied to clinical orthodontic patients undergoing treatment with removable functional appliances. Preliminary research findings suggest that the behavioral model described is a successful system for the introduction of a removable device to be worn by the patient. The techniques described also are useful for the previously uncooperative patient undergoing remedial treatment. Another major benefit of using this strategy is found in the response of the children's parents. The approach reduces the potential for and frequency of parent-child conflicts over dental health. Currently, a small sample of children are being treated by the behavioral method. Both parents and patients are involved. A specific schedule for wearing of a removable appliance is identified, along with parental observations and rewards based on patient compliance. Once the youngster is regularly meeting criteria, the program is altered to increase the desired response of appliance wear. The behavioral model has implications for various aspects of orthodontic care, including the use of such appliances as the Fr?nkel, Bionator, headgear, intraoral elastics, and proper lip posture. On the basis of this functional analysis of behavior, implications for treatment and prevention of noncompliance in orthodontic patients are discussed.     

A functional appliance system for the correction of class II relationships

A technique is described for the correction of Class II malocclusion involving a functional appliance and consisting of three phases. 1. Adjustment of posterior arch width and dental alignment, using semi-rapid maxillary expansion by means of an upper removable appliance, to co-ordinate the anticipated positions for the arches. 2. Correction of the Class II dental relationships using a modification of the twin-block functional appliance. 3. Retention, using an upper removable appliance with a very steep anterior bite plane. The technique is illustrated by a case report.

Correction of posterior crossbites: diagnosis and treatment

The correction of posterior crossbites is more complex than it appears. To develop an appropriate treatment plan, it is first necessary to determine if: (1) there is a functional jaw shift on closing; (2) the crossbite is unilateral or bilateral; (3) it is dental, skeletal, or a combination of both; and (4) it is related only to the maxilla or both jaws. Once the problem's apparent cause has been defined, it is then necessary to select the appropriate modality of treatment, which, in the maxilla, is: (1) usually a removable acrylic-based appliance with 1 or more transverse screws; or (2) a fixed Hyrax-type or Hass-type appliance. In the mandible, if dental expansion is required, the appliances most frequently used are the lip bumper or a removable acrylic-based appliance with a single screw lingual to the incisors. Once the appliance has been placed, it must be determined when adequate expansion has been achieved and how best to retain it.     

Three-dimensional evaluation of dentoskeletal changes after posterior cross-bite correction by quad-helix or removable appliances.

The aim of the study was to evaluate in a three-dimensional manner the dentoskeletal changes after slow maxillary expansion. The sample consisted of 34 children with a unilateral, symmetrical posterior cross-bite. Half of the children were treated with a quad-helix and the rest with a removable appliance. Assessment of the changes was made with study casts, and frontal and lateral cephalograms, before treatment, at the end of the expansion, after a retention period of 3 months, and after a post-retention period of 3 months. The results showed that sufficient expansion of the dental arches took place in both groups. The expansion expressed in the molar region in the quad-helix group was mostly due to buccal translation of the teeth and in the removable appliance group due to buccal tipping. The quad-helix group showed somewhat greater basal expansion than the removable appliance group, though the basal expansion in both groups was rather small. A tendency towards an increase of the NL/ML angle characterized the removable appliance group, but the opposite pattern was present in the quad-helix group.
