How Does Dental Crown Placement on Implants Work?
Dental crown placement is the final phase of the dental implant procedure. After the implants integrate with the bone, the dentist will schedule a second surgery to expose the top of the implant. A collar will be placed over it to guide the gum tissue for proper healing. Once the tissue heals, the collar will be removed and replaced with the abutment. Impressions of the abutment will be taken to make the dental crown. This article focuses on the procedure involved with dental crown placement.
The dental crown placement
After the abutment is screwed onto the implant and tightened, the dentist will place the temporary crown on the abutment. In some situations, a collar may not be necessary after the second surgery meaning the abutment and temporary crown will be placed immediately.
The temporary crown will remain there for about four to six weeks. The gum will heal around it for a natural appearance. The temporary crown is not as strong as the permanent crown. It is usually used to protect the implant from the forces of chewing before the permanent crown is ready, and allow the jawbone to get stronger.
During this period, the permanent dental crown will be produced by the dental lab. The production process may take about two to three weeks or less. The lab technician will use the impression of the teeth created by the dentist to create an accurate and realistic-looking artificial crown. Hence, the need for multiple dental appointments for the crown placement.
Choosing the new prosthetic crown
The dental expert will discuss the options available – patients can choose between removable, fixed or hybrid prosthetics.
Removable – this is identical to the regular removable denture and can be full or partial. The dental crown is enclosed at the base by gum-like plastic and mounted to a metal platform connected to the implant abutment. The mechanisms snap together securely but is removable for repair or routine cleaning.
Fixed – in this case, the dental crown will be permanently bonded or screwed onto the single implant abutment. The tooth is not removable for any reason. This is the most common scenario – fixing a crown on its dental implant. Since implants are incredibly strong, multiple teeth can be supported by a single implant if they are connected.
Placing the crown
After the dental lab has made the crown, the dentist will check to ensure that the crown was produced up to standard. This means checking the fit and appearance of the crown and matching it to the existing natural teeth before cementing it securely into place.
Local anesthesia will be applied to numb the area throughout the crown placement procedure. The dentist will use dental cement to bind the crown over the tooth. If necessary, minor adjustments may be made on the crown’s shape, especially if the patient’s teeth do not align correctly with the opposing teeth.
Once the dental crown is cemented or screwed into place over the implant, the result is a prosthetic tooth that looks almost like the natural teeth. The placement procedure is simple and requires about two dental visits.
