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.
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.
Space maintainers are very important in the prevention of malocclusions. Their indications and limits are described.
This manuscript provides the current standard passive space maintenance recommendations and identifies the appropriate space maintainer for premature loss of teeth in the primary dentition, early mixed dentition, and late mixed dentition.
An aesthetic solution is offered to the problem of space maintenance following the re-opening of space for an upper central incisor.
Early extraction of carious primary teeth may result in functional and/or loss of arch length problems. That is the rationale behind root canal therapy and/or space maintenance after the extraction of pulpally involved primary molars. What follows is a short radiographic and photographic history of unexpected results in well established and routine space therapy treatments.
Primary teeth play a critical role in the growth and development of a child. In addition to their role in esthetics, eating, speech, and to encourage normal function and resultant expected growth, the other main function of a primary tooth is to hold space for the permanent successor until it is ready to erupt. Space maintenance forms an integral part of preventive and interceptive orthodontics. After the premature loss of a tooth, not only do space maintainers maintain function and preserve arch length, they also maintain esthetics and eliminate any potential psychological damage a child could face as a result of the premature loss of teeth. The space maintainer also allows the permanent tooth to erupt unhindered into proper alignment and occlusion.

Five types of space maintainers were placed in 196 children participating in an extensive dental care program during a four-year study. Children with space maintainers were examined at six-month intervals. During the study, some sort of difficulty was encountered with 43% of the appliances inserted. The most common problem encountered was lost or missing appliances. Sixteen appliances had broken arch wires or loop wires; only ten broken bands were noted. Anther problem was distortion of arch wires. Suggestions are made for possible modifications in the space maintainers to reduce the incidence of problems.
