Marginal Ridge Thickness (Mrt) Of Maxillary Incisors, Mark Foster
Master's Theses (2009 -)
Aim: To determine the marginal ridge thickness (MRT) of maxillary incisors in orthodontic patients and the possible correlation between MRT and Bolton Index.
Methods: 120 pre<–>orthodontic treatment dental casts were collected, following the inclusion criteria: Quality pretreatment upper and lower casts, age 10<–>16, full permanent dentition (except 2nd and 3rd molars), no obvious wear/attrition/abrasion, no proximal restorations or crowns. For each cast, the mesio (M<–>D)distal (M<–>D) widths of the upper and lower teeth from left 1st molar to right 1st molar were measured to calculate Bolton Index. The MRTs of the maxillary incisors were measured in …
