The process of getting an onlay is similar to that of an inlay. Here are the steps involved in the onlay procedure:
Examination and Treatment Planning: Your dentist will examine your tooth to determine whether an onlay is the appropriate treatment option. They will assess the extent of decay or damage and evaluate the overall condition of the tooth.
Tooth Preparation: If an onlay is deemed suitable, your dentist will prepare the tooth to receive the restoration. This involves removing any decayed or damaged tooth structure. Local anesthesia will be administered to ensure your comfort during the procedure.
Impression Taking: After the tooth is prepared, your dentist will take an impression of the tooth using dental putty or a digital scanner. This impression will serve as a mold for the dental laboratory to fabricate the custom-made onlay. In some cases, a temporary restoration may be placed to protect the prepared tooth until the final onlay is ready.
Shade Selection: If the onlay is made of tooth-colored material like porcelain or composite resin, you may be asked to select the shade that matches your natural teeth. This helps in achieving a seamless and aesthetically pleasing result.
Temporary Restoration (If Necessary): Depending on the situation, a temporary onlay may be created to protect the prepared tooth while you wait for the permanent onlay to be fabricated.
Laboratory Fabrication: The dental laboratory receives the impression of your tooth and uses it to create the custom onlay. Skilled technicians will design and fabricate the restoration to fit your tooth precisely. The laboratory process typically takes a few days.
Bonding the Onlay: Once the permanent onlay is ready, you will return to the dental office for the final fitting and bonding. The dentist will remove the temporary restoration (if present) and check the fit, shape, and color of the onlay. If everything is satisfactory, the onlay will be bonded to your tooth using dental cement or adhesive. The dentist will ensure proper placement and make any necessary adjustments to achieve an optimal fit and bite.
Polishing and Final Adjustments: After the onlay is securely bonded, the dentist will polish it to achieve a smooth and natural appearance. They will also check your bite and make any final adjustments to ensure that the restored tooth functions properly with the opposing teeth.
The process of getting an onlay may require two dental visits, similar to an inlay procedure. The specific details and timeline may vary based on the complexity of your case and the availability of an in-house dental laboratory. Your dentist will provide you with instructions on caring for your onlay after the procedure. It's important to maintain good oral hygiene and attend regular dental check-ups to ensure the longevity and health of your restoration.
Onlays are used in dentistry to restore and repair teeth that have moderate to extensive damage or decay. They are versatile restorations that offer several uses and benefits. Here are some common uses of onlays:
Large Cavity Restoration: When a tooth has a large cavity or extensive decay that cannot be effectively treated with a regular dental filling, an onlay can be used to restore the tooth. The onlay covers a larger surface area and provides more support and protection to the remaining tooth structure compared to a filling.
Fractured or Cracked Teeth: Onlays are an excellent option for restoring teeth that have minor fractures or cracks. They can strengthen the tooth and prevent further damage by providing a stable and durable restoration.
Tooth Wear and Erosion: Teeth that have experienced significant wear or erosion due to factors such as teeth grinding (bruxism) or acid erosion can benefit from onlays. The onlay can restore the natural shape and structure of the tooth, protecting it from further deterioration.
Aesthetic Enhancements: Onlays can be made from tooth-colored materials like porcelain or composite resin, which can be matched to the natural color of your teeth. This makes them an ideal choice for improving the appearance of a tooth that has visible decay, discoloration, or other cosmetic concerns.
Replacement for Large Fillings: When an existing filling is deteriorating, an onlay can be used to replace it and provide a more durable and long-lasting restoration. Onlays are custom-made to fit the tooth precisely and provide better strength and longevity compared to large fillings.
Conservative Approach: Onlays are considered a more conservative option compared to dental crowns. They preserve more of the natural tooth structure as they only cover the damaged or decayed areas, while the healthy tooth structure is preserved.
Longevity and Durability: Onlays are known for their strength and durability. They are made from materials that can withstand biting forces and function similar to natural teeth. With proper care and maintenance, onlays can last for many years.
It's important to note that the suitability of an onlay depends on the specific condition of your tooth. Your dentist will evaluate your oral health and recommend the most appropriate treatment option for your situation.
