In the altered frenulum, the highest frequency was with fixing between the middle third and the apex/inferior alveolar crest
Contour correction of the alveolar crest
was performed using a stainless-steel drill, and soft-tissue reduction was also performed.
Model of initial translational motion of tooth root in PDL: 1--tooth crown; 2--dental alveolus; 3--tooth root; 4--periodontal slit of constant thickness normal to root surface; F--concentrated force acting on the tooth crown; M = Fd--couple (couple is orthogonal to the xy-plane); d--distance between application point of force and centre of rotation P; a--radius of tooth root cross-section at level of alveolar crest
; h- -height of tooth root; [delta]--width of PDL in horizontal plane [x.sub.1][0.sub.1][y.sub.1].
Mean distance between alveolar crest
and superior margin of MF was 10.6 mm on right side and 10.3 mm on the left side.
Preservation of AP anatomical integrity aiming at prevention of post-traumatic alveolar crest
deformity is an urgent problem in surgical dentistry.
Two months after extraction he noticed facial deformity and swelling at the left side of the mandibular alveolar crest
, and was referred to the dentistry clinic.
The typical radiographic appearance is that of a triangular or semicircular radiolucency with the narrow part of the lesion toward the alveolar crest
, often with a radiodense border, and located within the alveolar process between the roots of teeth.[1-4] Root resorption has been described.
The final sample for this assessment was 200 first and second maxillary premolars, in which was measured the distance from premolar apex to the closest point from MSF (Measure A'), and the depth from the middle of the line that join the alveolar crest
to the maxillary sinus floor (measure B').
Such movements generate forces that applied to the incisors and focused mainly at the alveolar crest
[Tables 1 and 2].
An imaginary line was drawn vertically to the infraorbital foramen intersecting with the top of alveolar crest
. The starting point of the implant was 5 mm to the palatal side from the intersection point.
The reflection of the palatal flap was limited to the most coronal portion of the alveolar crest
. Minimally traumatic extractions were performed.
(from the inferior border of the mandible to the alveolar crest
divided by from the inferior border of the mandible to lower edge of the mental foramen) in dentulous mandible.
