Treatment guidelines

Mouth opening

Key points

  • Patients may present with small mouths, or limited mouth opening due to trauma, surgical interventions, sclerodermia, scars or muscular and Temporo-mandibular disorder (TMD).
  • Limited access due to a small mouth or due to limited mouth opening is an important diagnostic factor when treating patients with dental implants in the posterior region.
  • In the anterior region limited access does not usually interfere with regular treatment.

Single implants and their restoration
In the posterior aspect of the mouth where vertical space is limited to the inability of a patient to open sufficiently wide, the angulated screw channel allows the screwdriver to tighten the abutment screw without requiring as much vertical opening due to mesial inclination of the channel in the crown.

The Temporomandibular Joint
Biomechanical studies of the relationship between and cranial form and function have frequently appeared in dental and engineering literature since the mid-to-late 90s. It is known that deformation of the cranial vault occurs during contraction of the temporalis muscle, most particularly the anterior portion of the muscle (Fitton et al, 2012). Craniofacial osseous stress and strain occurring during mastication is moderated by the unique, complex suture types found throughout the skull.
