MINI DENTAL IMPLANTS – implants that are smaller in diameter compared to conventional dental implants. The placement procedure of these implants is less invasive, resulting to very minimal to no downtime and trauma for the patient. Mini implants are often used to give support to removable dentures, which can immediately be used after the mini implants are placed.
MOUTH GUARD – a soft, comfortably-fitting dental device that protects the teeth and inner mouth area from injuries or accidents.
NERVE REPOSITIONING/LATERALISATION – the process of moving or repositioning the inferior alveolar nerve prior to the dental implants placement. This process is necessary when the patient has insufficient bone mass in the lower jaw bone, and the placement of dental implants will not be possible without damaging the inferior alveolar nerve (thus the need for the nerve’s repositioning).

RESTORATIVE DENTISTRY – a dentistry specialty dealing with the restoration of diseased, missing or damaged teeth to their natural function and form.
ROOT CANAL THERAPY (RCT) – a dental procedure used to save a tooth that has been abscessed. During a root canal therapy, the pulp chamber is cleaned thoroughly, disinfected and closed with a permanent dental filling.
ROOT FORM IMPLANTS – also called “endosseus” or “endosteal” implants, these types of dental implants are the most common ones used worldwide. They are inserted directly into the jawbone, and have two sub-types: cylindrical and screw.
ROOT PLANING – the process of removing hard deposits from the surface of the tooth root, which is below the gum line.
SEDATION DENTISTRY – also known as “sleep dentistry”, sedation dentistry allows a patient to feel relaxed during dental treatments. Sedation dentistry is effective in enabling patients who have dental phobias to get the dental treatments they need, without having to feel fear or anxiety.
SINUS GRAFTING – also called a “sinus lift”, sinus grafting is the procedure of lifting the sinus membrane to introduce a bone graft onto the sinus floor; this procedure is done when there is insufficient bone mass in the sinus area to support a dental implant.
SUBPERIOSTEAL IMPLANTS – custom-made dental implants that are positioned above a patient’s jaw bone, but underneath the gum line. The lightweight metal framework of subperiosteal implants is usually used to secure a patient’s dentures in cases when the jaw bone is insufficient because it has atrophied or receded.
