Orthodontic space maintenance--a review of current concepts and methods.

Crowding and a lack of space in the permanent dentition are amongst the most common orthodontic problems encountered in orthodontic patients. Often the aetiology of these problems is linked to premature loss of one or more deciduous teeth with corresponding loss of space. Many of these cases could have been prevented or their severity alleviated if the practitioner employed adequate planning and space maintenance during initial treatment in the mixed dentition. A review of some of the current orthodontic space maintenance appliances and their indications is presented along with a table to aid the practitioner in treatment planning.

Radiographic success of ferric sulfate and formocresol pulpotomies in relation to early exfoliation.

PURPOSE: The purpose of this retrospective study was to evaluate the radiographic findings with formocresol and ferric sulfate pulpotomies in relation to early tooth loss. METHODS: Vital pulpotomies with either ferric sulfate or formocresol, performed by faculty members between 1992 and 2002 at The University of Iowa, were evaluated retrospectively. Radiographic criteria were established to assess success or failure of the treated tooth. This was then correlated with time of tooth loss and space management. RESULTS: Eighty-five molars, followed between 6 to 61 months, met the inclusion criteria. Of these, 15 (43%) teeth treated with ferric sulfate, 23 (56%) treated with formocresol, and 5 (55%) treated with a combination of ferric sulfate and formocresol remained free of any radiographic pathology. Overall, 13% of the pulpotomized teeth were prematurely lost due to abscess formation and in need of space management. Regardless of the treatment type, internal root resorption was the most common cause of premature exfoliation. CONCLUSIONS: Both ferric sulfate and formocresol pulpotomies can lead to premature exfoliation of primary teeth, with the subsequent need for orthodontic space maintenance. Therefore, radiographic criteria should be taken into consideration when evaluating pulpotomized teeth at recall visits.

The swaged crown: its modern applications.

The authors makes no claim for originating the technique of construction and the use of the swaged crown. He was introduced to the swaged crown over a quarter-century ago by the late Dr. Benjamin Weiss, and orthodontist, and his technician, Sanford Pollock. Clinical adaptations of the swaged crown followed. The swaged crown has proved to be a versatile solution to a number of clinical problems occurring in the primary, mixed, and early adult dentitions. It provides simplicity of use, strength, and durability of appliances, and virtual freedom from decalcification and caries for the covered teeth. Chair-time procedures are kept to a minimum, and laboratory costs are reasonable. All appliances require supervision and maintenance by the dentist. When swaged crowns are used, the time and effort involved in such supervision and maintenance are kept at a minimum. This time is considerable less than that required, when even well fitted orthodontic bands are used, instead of swaged crowns.

Space maintenance in the primary and mixed dentition.

The maintenance of arch length in the primary, mixed and early permanent dentition is important for the normal development of the occlusion. Premature loss of primary teeth can result in the loss of arch length leading to malocclusion. Space maintenance can often prevent space loss and either prevent the development of a later malocclusion or reduce its severity. The pattern of space loss depends on many factors including age, stage of development, which teeth have been lost, the presence of crowding or spacing, and occlusal relationships. Careful consideration of many factors is required when deciding whether space maintenance is indicated. Radiographs and space analysis can be helpful. Space maintainers can be fixed or removable. Band and loop space maintainers have fewer problems than other types. Frequent follow-ups to check for any problems following space maintainer insertion is recommended.

Traumatic avulsion of the mandibular right primary lateral incisor and cuspid.

Premature loss of the primary mandibular cuspid has been considered rare. When this occurs, however, space maintenance should be considered to prevent distal drifting of the lateral incisor. The purpose of this case report was to document traumatic avulsion of the mandibular right lateral and cuspid. A lingual arch appliance with a spur was fabricated to maintain space and prevent movement of the mandibular incisors. Sequelae of premature loss of primary teeth is presented.

Direct bonding applied to space maintenance.

Based on the conditions of this study, the following conclusions were reached: A success rate of 70 percent seems to justify further investigation into direct bonded space maintainers. A space maintainer directly bonded to the buccal surfaces seems to be efficient in maintaining single tooth spaces. Primary-to-primary appliances were more successful than the primary-to-permanent appliances, which suggests that incomplete first permanent molar eruption and a posterior location affect appliance durability.
