Functional Jaw Orthopedics, Craniofacial Anomalies, Orthognathic Surgery and Orthodontics
Orthodontic forces influence tooth position and direction of bone growth. Dr Tierney evaluates the jaw position in three dimensions:
- Sagittal Plane - Anteroposterior; buck teeth; deficient lower jaw, profile; overjet.
- Transverse Plane - Right to left; constricted upper jaw; crossbite; palate expander.
- Vertical Plane - top to bottom; deep bite; open bite; ‘gummy smile.’
Dr. Tierney’s training provides her with a deep understanding of both aesthetics and function. This uniquely qualifies her to diagnose, treat and manage conditions, defects, cleft palates, craniofacial syndromes, and injuries of the mouth, teeth, jaw and face.
Optimally, skeletal dysplasia (disproportion/malocclusion) in young patients should be treated as a skeletal problem. Altering the direction of growth via jaw orthopedics to produce a more ideal skeletal relationship should be attempted. Sometimes in milder skeletal discrepancies/malocclusions tooth position can be altered for an orthodontic compensation to a skeletal problem.
Orthognathic (jaw) surgery by a qualified Oral and Maxillofacial Surgeon or a Plastic Surgeon is recommended when a moderate to severe dental-skeletal disharmony exists. Dr. Tierney works in conjunction with the surgeons to attain optimal dental and facial balance. Pre-surgical orthodontic treatment (braces) is usually necessary. The surgery is generally performed on non-growing patients.
