Bruxism and effective restoration with 3M Oral Care

Bruxism is thought to affect around 8-10% of the population and is characterised by excessive tooth grinding and jaw clenching. There are numerous causes of bruxism and its implications can be devastating. There is no cure for bruxism, but its symptoms can be managed for improved comfort, function and aesthetics.

Awake bruxism (AB) and sleep bruxism (SB) are two separate conditions – SB is considered a sleep-related movement disorder, while AB is thought to be influenced largely by psychosocial factors such as anxiety, stress and personality characteristics which haven’t as yet been linked quite as clearly to SB.

Sufferers might complain of orofacial pain, headaches, tooth sensitivity, ear aches and may also present with severely worn/broken teeth. In more severe cases, bruxism may be one of the causes of temporomandibular disorders (TMD). Aside from worn down teeth, bruxism can also accelerate aging in the lower face due to the parafunctional habit and muscle hyperkinesis.

The functional and mental ramifications of bruxism and tooth wear have been compared to that of edentulism, and it can be considered a silent enemy as most sufferers are unaware that they are routinely grinding their teeth or clenching their jaw.

Restoring aesthetics and function in bruxist patients is of the utmost importance with treatment options guided by the severity of the condition – patients may require a multidisciplinary approach to care, which might include periodontal and endodontic surgeries, for instance.

Patients may very well require treatment to minimise the future impact of bruxism which might include wearing a mouthguard at night, receiving botulinum toxin (Botox™) injections, undergoing physical therapy for muscle relaxation or even taking medication for stress.

Oral rehabilitation will depend on various factors, such as the patient’s style of bruxing, periodontal health, medical comorbidities and other conditions that could complicate rehabilitation. Fractures are one of the more commonly reported failures pertaining to bruxism-related tooth wear.

In severe cases, dental crowns may be indicated; materials such as gold and porcelain-fused-to-metal (PFM) have been noted for their durability and effectiveness when restoring worn dentition in bruxists, in addition to zirconia.

Advanced clinical techniques mean dental professionals can conserve more of the natural soft and hard tissues, while still providing satisfactory outcomes, with direct or conservative indirect restorations such as veneers and onlays/inlays.

The use of minimally invasive adhesive techniques has also been noted as an effective, conservative option for the rehabilitation of worn teeth. In comparison with conventional restorations, adhesive protocols grant clinicians the flexibility to repair or replace the restoration should breakages/fractures occur.

For such indications Scotchbond Universal Plus from 3M Oral Care provides outstanding adhesion and is universally suitable for direct and indirect restorations*. Clinicians are provided with gold standard adhesion to all dental and restorative substrates using a one-bottle system without the need for a separate primer or silane.

There is minimal post-op sensitivity for enhanced patient comfort and the flip-top vial provides convenience for professionals, allowing for one handed, clean dispensing.
