Grinding or Clenching

The act of grinding or clenching adds excessive forces onto the joints that may cause a disruption in the equilibrium of the complex.

Dislocation of the Joint

The misalignment of the joint or the displacement of the tissue that separates the ball and socket of the TMJ complex.

Stress

Leads to the tightening of facial and jaw muscles, resulting in parafunctional habits.

Miles of Smiles

TEMPOROMANDIBULAR JOINT DISORDER, TMJD (in the medical literature TMD), or TMJ syndrome, is an umbrella term covering acute or chronic pain, especially in the muscles of the face, and/or inflammation of the temporomandibular joint. The mandible (lower jaw), and specifically the two joint complexes associated with it, has the unique characteristic of having two ranges of motion. The first is a pure rotational movement, and the second is a translational motion or actual physical movement down the slope of the skull.Signs and symptoms of temporomandibular joint disorder can vary in their presentation and can be very complex, but are often simple. On average the symptoms will involve more than one of the numerous TMJ components: muscles, nerves, tendons, ligaments, bones, connective tissue, and the teeth.

Due to the proximity of the ear to the temporomandibular joint, TMJ pain can also be confused with ear pain. The pain may be referred, in around half of all patients, and experienced as an earache. People with TMD can experience severe pain and discomfort that can be temporary or last for many years. More women than men experience TMD, and is seen most commonly in people between the ages of 20 and 40.(Continued on Page 3)

Personal Touch

Dr. Roy Yanase was born in Honolulu, Hawaii in July of 1942. He moved with his family to Torrance, California to begin his junior year in high school. It didn’t take long for him to get a c c l i mat e d a n d g a i n th e admiration and respect of his peers, where as, senior he was elected student body president of Torrance High School. From early on anyone who knew Roy recognized the multitude of distinguishable characteristics in him. Even to this day the

principal of his high school, at the age of 87, has followed Roy in his achievements through the years and has become a patient in the practice. Dr. Roy Yanase graduated from Herman Ostrow School of Dentistry at USC in 1969. His father, Dr. Stanley Yanase, also graduated from USC Dental School in 1938, as well as his son, Dr. Rex Yanase in 2002. Ambition, excellence and integrity is in the Yanase genes. In 1985, encouraged by Professor P.I. Brånemark, the father of implant dentistry, Roy was one of the f o u n d i n g m e m b e r s o f t h e Osseointegration Study Club of Southern California, and later helped organize the Osseointegration Study Club of Japan in 2001. He is an active member of numerous Prosthodontic, dental, and implant organizations, and a Co-Director of the Odontic Seminar at the Ostrow School of Dentistry of USC. Roy has served as the president of the P a c i fi c C o a s t S o c i e t y o f Prosthodontics in 1999, bringing together speakers, members, and guests from the Pacific Rim, England, and Europe to Coronado Island in San Diego. Dr. Yanase was elected to serve a 7-year term as an examiner on the American Board of Prosthodontics, and completed his term in 2009 as the president. In 2010, Loma Linda University awarded him the Kenneth Wical Award for Excellence in Prosthodontics and in 2012, he received the American College of Prosthodontists

President’s Award for leadership, and academic contributions to prosthodontics. Most recently he will be recognized in June of this year with the Pacific Coast Society for Prosthodontics Fred E.

Gulick Distinguished Life Member Award. To list out his professional accomplishments would require a novel, but that is not what distinguishes Roy Yanase the most. His passion for dentistry is equated by his love for his family, friends

and colleuges. It is his generosity in being available to the profession and his colleagues that no book can describe. Roy is an approachable person, and a mentor for the community. His honesty in sharing the truth in dentistry, and evidenced based knowledge is to be much respected. Today, Roy and his wife Regina have been married for the past 44 years and live in Torrance. eir son Rex organized the Yanase Dental Group where Dr. Stanley started the practice in 1958. ey enjoy traveling in their leisure time, and just returned from

their annual trip to Japan. His hobbies include dentistry on stamps, dental antiques, and anthropology. It is Roy’s true love and passion for his family and dentistry, and his devotion to the real and important issues in life, that grants him success and distinguishes him as a dedicated and compassionate dental professional.

Trauma to the joint complex can l ead to inflammation of the intra-articular disc and as a result a sharp shooting pain will persist

until the inflammatory process passes. The trauma is a result of any pressure or impingement on the disc by the condyle. It is common for trauma to occur during normal function where the disc may be out of place.

The temporalis muscle is a large fan muscle that lays above the ear. Its fibers have three branches and plays a large part in closing the lower jaw. Often times tension in this muscle leads to headaches, more frequently in the morning. Tenderness in this muscle has a high correlation with moderate to heavy grinding habits.

Muscle Tension

Inflamed Joint

Temporalis Muscle

The masseter muscle is the large strap muscle that cradles the lower jaw from the outside. When the jaw closes, it has the major role in generating force when crushing food and during buxism. Soreness of this muscle, l ike the temporalis and medial pterygoid,, is an indicator that there is significant parafunctional habits taking place.

Tightening of the muscles in the face is the most common symptom experienced. Muscle tension does not necessarily imply the existence of TMD, but more an indication of the existence of parafunctional habits (grinding & clenching). It can be attributed to several causes,

physical trauma, stress, and malocclusion.

Masseter MuscleDamaged Joint

The media l p t e r y g o i d muscle is the sma l l s t rap musc le that c rad les the lower jaw from the inside . It cradles the jaw bone and during contraction has a complimentary role in generating force to crush food. Soreness of this muscle is less noticeable than in other muscles of chewing.

Medial Pterygoid Muscle

As t rauma to the jo int cont inues and the inflammatory process persist, the body cannot continue repairing the constant damage to the complex. Permanent changes to the joint occur and can be seen as bony degeneration of the bony condyle, deterioration of the articular disc or both. Therapy includes therapeutic symptomatic management, and in extreme situations surgical

therapy and correction.

BLEACHING TRAYS

WHITENING STRIPS

IN OFFICE WHITENING

Everybody loves a bright white smile, and there are a variety of products and procedures available to help you improve the look of yours. Many people are satisfied with the sparkle they get from daily oral hygiene and regular cleanings at the dentist’s office, but if you decide you would like to go beyond this to make your smile look brighter, you should investigate all of your whitening options.

50 SHADES OF TOOTH WHITENING...

Start by scheduling your complimentary consultation with Dr. Rex or Dr. Hamilton to review what options are available to you. Whiteners may not correct all types of discoloration. For example, yellowish hued teeth will probably bleach well, brownish-colored teeth may bleach less well, and grayish-hued teeth may not bleach well at all. If you have had bonding or tooth-colored fillings placed in your front teeth, the whitener will not affect the color of these materials and they will stand out in your newly whitened smile. You may want to investigate other options, like porcelain veneers or dental bonding.

has thrown at you. When something wonderful happens, you can’t wait to tell them about it, knowing they will share in your excitement. They are not embarrassed to cry with you when you are hurting or laugh with you when you make a fool of yourself. Never do they hurt your feelings or make you feel like you are not good enough, but rather they build you up and show you the things about yourself that make you special and even beautiful.“

― Bob MarleyCongratulations to Dr. Rex Yanase and his wife Hoai Nguyen, who on September 8, 2012 celebrated their wedding with their closest family and friends.

“Only once in your life, I truly believe, you find someone who can completely turn your world around. You tell them things that you’ve never shared with another soul and they absorb everything you say andactually want to hear more. You share hopes for the future, dreams that will never come true, goals thatwere never achieved and the many disappointments life
