The ectopic loss of maxillary primary canine occurs less frequently than does mandibular loss. When it occurs, ectopic loss of maxillary primary canine typically reflects a very distal eruptive displacement of permanent lateral incisors and not necessarily a significant tooth mass problem. Resultant crowding and blockage of permanent canine may occur because it erupts too late in normal ______.

Study Notes
Space Maintainers
- A transpalatal bar space maintainer is a type of space maintainer.
- A distal shoe space maintainer is indicated when there is premature loss of second deciduous molar before eruption of first permanent molar.
Indications and Contraindications
- A distal shoe space maintainer is used when there is one tooth lost on one quadrant due to the limited strength of the anchor tooth.
- A transpalatal bar space maintainer is indicated when one side of the arch is intact and several primary teeth are missing in the other side.
- A Nance appliance is preferred when both primary molars have been lost bilaterally as both permanent molars tip mesially with the transpalatal arch.
- A distal shoe space maintainer lacks functionality compared to other types of space maintainers as it is non-functional.
- Poor oral hygiene is a contraindication for using a distal shoe due to inadequate oral hygiene.
- The presence of medical conditions is a concern when using a distal shoe to prevent complications such as subacute bacterial endocarditis.
Types of Space Maintainers
- A band and loop space maintainer is a unilateral, fixed, non-functional, and passive space maintainer used when a single tooth is missing in the posterior segment.
- A passive lingual arch appliance is a bilateral, fixed, non-functional, and passive space maintainer used for the lower arch.
- A Nance palatal arch space maintainer is a bilateral, fixed, passive, and non-functional space maintainer for the upper arch.
Concerns and Consequences
- The main concern with the loss of mandibular primary incisors is based on esthetic, speech, and functional concerns.
- Early loss of lower primary incisors is generally due to ectopic eruption of permanent incisors in reflecting excessive incisor crowding.
- The major consequence of early loss of maxillary primary incisors includes esthetic, speech, and functional concerns.
- Premature loss of deciduous teeth can lead to issues such as poor esthetics, speech problems, and narrowing of the dental arch.
- The consequence of early loss of lower primary canine includes shift in midline toward side of loss, lingual collapse of incisor segment, and possibly deepening of overbite.
Treatment Options
- A lingual holding arch may be used with spur attachments to control incisor positioning and prevent encroachment on permanent canine eruption positions when primary canines are lost early.
- An anterior appliance incorporating artificial primary teeth may be considered to satisfy aesthetic and functional needs.
- Acrylic partial denture has been successful in replacement of single and multiple maxillary primary teeth.
