Management of infra-occluded primary molars

Abstract

This article reviews the aetiology, diagnosis and management of infra-occluded primary molars. The different treatment options are detailed as well as the differences in the management of patients depending on their age, the severity of the infra-occlusion and whether the permanent successor is present or absent. CPD/Clinical Relevance: The ability to identify and diagnose infra-occluded primary molars is crucially important for their subsequent management. Knowledge of the different treatment options and their relevance in different clinical situations is important for all dental healthcare professionals.

Tooth agenesis: An overview of diagnosis, aetiology and management

“…Up to 65.7% of individuals with missing second premolars have infra-occlusion of the corresponding primary molar [15] , [76] . Management of the infra-occluded primary molar, without a permanent successor, depends on the: Degree of infra-occlusion Age of the patient Likely progression of the infra-occlusion Prognosis of the infra-occluded tooth and Whether adverse effects of the infra-occlusion are present, such as a centreline shift to the site of the infra-occlusion and tipping of adjacent teeth toward site of the infra-occluded teeth [95] .

“…Whether adverse effects of the infra-occlusion are present, such as a centreline shift to the site of the infra-occlusion and tipping of adjacent teeth toward site of the infra-occluded teeth [95] .…”

“…It must be noted that the small step present between an infra-occluded primary molar and adjacent teeth may be due to differences in crown heights rather than the infra-occlusion. Moderate infra-occlusion occurs when the occlusal plane of the infra-occluded tooth is between the contact points and the alveolar crest, and the severely infra-occluded tooth is below the alveolar crest [95] .…”

Eruption disturbances in the mixed dentition: orthodontic considerations for primary dental care

“…The evidence base regarding an infra‐occluded primary molar is greater than that related to the other eruption disturbances discussed in this review. Several papers providing guidance on its diagnosis and management have been published 75–78 . Infra‐occlusion occurs when a tooth is positioned below the occlusal plane and is usually associated with primary molars (Fig.…”
