Overerupted teeth are often sharp due to lack of tooth wear (dental attrition) by adjacent teeth during chewing. [citation needed] Overeruption is treated either by forcing the tooth back using orthodontic techniques, or by cutting the interfering part of the tooth and installing a crown. [citation needed]
Therefore, the Dahl concept is a more conservative technique to increase OVD. The Dahl concept is the relative axial tooth movement that is observed when a localised appliance or localised restorations are placed in supra-occlusion and the occlusion re-establishes full arch contacts over a period of time.

Primary failure of eruption (PFE) is a rare disease in which tooth eruption does not occur despite space in the arch for eruption. Non-eruption of non-ankylosed teeth occurs due to an eruption mechanism that has failed leading to a posterior unilateral/bilateral open bite. [28] Infra occlusion is the primary hallmark of PFE.
The direction of the tooth movement must be carefully checked to ensure no tilting or movement of adjacent teeth occurs. [citation needed] Forced tooth eruption can also be performed with fiberotomy. This technique is adopted when gingival margins and crystal bone height are to be maintained at their pretreatment locations.
For technique 1, a wax pattern is designed on the die from the cast impressions and for technique 2 the wax is packed into the tooth preparation in the mouth and adapted the shape of the cavity. [28] Inlay wax is chosen due to its brittleness – it breaks upon removal from undercut of a cavity, either on the die or in the mouth.
The Hall technique can also be used with permanent first molars in some cases where prognosis is poor, such as where first permanent molars are hypomineralised, carious with poor prognosis but to be maintained until full eruption of second molars, or for cuspal coverage of endodontically treated teeth in minors with compliance issues preventing ...
Judicious reproximation disking of primary teeth with no tooth extraction is an occasional option. This decision depends on the careful tooth size-arch length evaluation. The amount of crowding, the arch length requirements, whether they are symmetric, and the state of health of the investing tissues are factors that continually impact the ...
In case of non-vital pulp: 1. Isolate the tooth with a rubber dam 2. perform root canal treatment. 3. Mix MTA and insert it to the apex of the tooth, creating a 3 mm thickness of plug. 5. Fill the canal with sealer and gutta percha. Alternatively, revascularization techniques are being used where an antibiotic is locally administered.
