Mouthguards for Protection
& Performance
By Stephen David Smith,
D.M.D., Paoli PA.
Dr. Smith has been providing oral
appliances to patients for over 30 years. He has researched, designed, and
published a number of unique modifications for TMJ, sleep apnea, and athletic
protection/performance as the individual need
arises
Mouthguards/personal protection equipment items are used in
contact sports to prevent concussions, orofacial, jaw/TMJ and teeth injury.
They are made from individual dental full arch impressions/casts. The models of
the maxilla and mandible are referred to the laboratory for fabrication to our
specifications. Depending upon the level of contact intensity, multiple-
laminated layers are used to reinforce the shock zones to cushion blows and
jarring.
Contact Sports:
Maxillary guards are for football, basketball, baseball, wrestling, lacrosse,
soccer. A strap attachment can be fused to the mouthguard with break-away
release, for the helmeted sports. Extra thickness highly dense multi- layered
material is designed for the heavy contact sports: boxing, kick boxing, ice
hockey, field hockey, martial arts. These are where blows to the face and jaw
are anticipated. A variety of colors/multiple styles can be custom selected.
Non-Contact Sports such as track & field, bowling, skiing, golf,
tennis, swimming, weight lifting, gymnastics can allow for a lower arch
mouthpiece. This provides easier speech, less bulk. There are a number of
design options. Design is dictated by the level of protection needed.
Performance: Much
publicity is being drawn to "new findings" relating the jaw/posture and TMJ and
associated muscles to increased strength. The finding that performance can be
enhanced by a properly designed mouthguard/mouthpiece is not a new discovery.
Published research in this field goes back to the 1970's, with a number of
dentists observing their patient, who reported increased strength, fatigue
resistance, and greater work capacity after treatment with oral splints. An
early publication on this field was by Stephen D. Smith, D.M.D.: "Monograph:
Dentistry in Sports Medicine". Further research has garnered more light on the
TMJ-Jaw/performance connection. Pivotal posterior, balanced molar support and
freedom from TMJ stress are critical elements of a successful design to
maximize patient/athlete benefit. Statistics have been compiled in all areas of
sports showing "before vs. after". Results reported are improvement in
lift/jump capacity, better scores, less energy output, increased weight/lifting
capacity, longer driving in golf, faster running and swimming times, etc.
Strength/output, endurance improvement are testimonials from patients/athletes
receiving these types of professionally custom made appliances.

Our office provides the services in
designing and fitting mouthpieces: from the professional athlete to the college
level player, to the everyday sports enthusiast who wants a performance
"boost".
A few applications are shown:
| Store-bought stock
tray or "boil and bite" mouthguard: These are low cost items and provide a service to the public of protection, particularly for team sports and for the mixed dentition/teenagers. The issue of comfort, bulk and precise fit is a variable. The patient does his/her own home- fitting and oral adjustments, and replaces the mouthguard seasonally. |

| Custom-fitting
mouthguard/mouthpiece: These are made through the dental office and laboratory, and involve more time, expense, and professional expertise. Impressions are done after a dental examination and prophylaxis/ cleaning, and models made. The specific sports requirements/requests are assessed individually. A bite registration is made. This may be modified depending on the patient/athletes jaw pattern and correlated to the maximum intercuspal neuromuscular position. Kinesiologic muscle testing may help verify the best anticipated bite registry. The design incorporates dental physiology, dental stress reduction, including compensating for missing or malpositioned teeth. Laboratory fabrication and processing from the plaster models is done from the specific prescription by the dentist. At return visit, the appliance is inserted and any adjustments made, including final tuning/ precision adjusting of the biting surface to a maximum strength position. This applies to both an upper or lower mouthguard/mouthpiece. At delivery, long-term care and maintenance is discussed. |

A major reason to have a qualified
dentist involved in the design and delivery of sports mouthpieces is the
professional dental consultation and examination. The dentist can advise the
patient of any other related findings, dental/periodontal disease, TMJ or jaw/
bone problems.
