Description and comparison: PUPC 13/37 is an elongated molar, narrower distally than
mesially (Fig.
(2018) - A smaller total root resorption crater volume was found in the LLLT group than the control group, on both tension and compression sides,
mesially and distally.
Therefore, taking occlusal plane as reference would be better compared to mandibular plane or palatal plane so that buccal tube can be tipped
mesially or distally, depending on the planned end relationship of molar.
The skeletal malocclusion Class I also known as neutrocllusion occurs when the maxilla and mandible are in harmony with each other, Class II which is also known as distoocclusion occurs when the mandible is distally positioned in relation to maxilla and is further divided into two sub divisions and Class III which is also known as mesioocclusion occurs when mandible is
mesially positioned in relation to maxilla.
The upper molar was attempted to move
mesially but because of the pneumatization of the maxillary sinus, this movement was not completed.
Upper molar space closure can be rapid as second molars rapidly move
mesially during treatment.
As a consequence, if the premolars or incisors (or both) are the anchoring teeth, they move
mesially, the incisors protrude, and overjet increases.
The maxillary second premolars moved
mesially 2.00 mm with tipping of 7.48deg.
As the first permanent molars drift
mesially after premature loss of primary molars, they exert a greater force on the anterior segment (incisors and primary canines) subsequently causing a horizon- tal overlap leading to dental crowding.27 The higher incisor crowding in the study population than in other population might be due to the high prevalence of dental caries among Saudi children.36 As the arch length decreases due to anterior and/or posterior car- ies lesions, the prevalence of anterior crowding be- comes higher.
Nearly 98% of posterior teeth tilt
mesially when subjected to occlusal forces.
Most commonly found buccally rotated teeth are premolars with buccal surface facing
mesially and lingual surface distally.
At this time teeth 13 and 23 were erupting, 23 was erupting
mesially for 63 and 53 had exfoliated.
