New anesthetic techniques for maxillary teeth avoid lip and facial numbness, improving esthetic dental assessments. These methods are beneficial for anterior esthetic restorative procedures.

Area of Science:

  • Dentistry
  • Anesthesiology

Background:

  • Esthetic restorative dentistry is a growing part of general practice.
  • Assessing anterior restorations requires natural lip and smile line harmony.
  • Traditional anesthesia distorts facial features, hindering esthetic evaluation.

Purpose of the Study:

  • To introduce and evaluate novel local anesthetic techniques for maxillary teeth.
  • To address the challenge of facial distortion caused by traditional anesthesia during esthetic dental procedures.

Main Methods:

  • Description of two new injection techniques: the anterior, middle superior alveolar block and the palatal approach anterior superior alveolar block.
  • Focus on achieving anesthesia of maxillary teeth without affecting facial expression muscles or soft tissues.

Main Results:

  • These techniques effectively anesthetize maxillary teeth.
  • They avoid the undesirable numbness of the face, lips, and muscles of expression.
  • Preliminary findings suggest they are useful for esthetic restorative dentistry.

Conclusions:

  • The anterior, middle superior alveolar block and palatal approach anterior superior alveolar block are promising additions to local anesthetic options.
  • These techniques are particularly valuable for dentists performing anterior esthetic restorative procedures.
  • Further safety and efficacy studies are warranted.
