Dental Implant-Fixing a poor fitting denture due to a lack of jaw bone

Background

Mr H had a set of poor fitting dentures due to a lack of bone in both his upper and lower jaw. He did not wish to have bone grafting to make up for this loss.

Treatment

The Treatment Plan for Mr H was devised such that six implants in the upper jaw were inserted to produce a locator framework for the upper over denture. In a similar manner six implants were also fixed to his lower jaw thus providing a further locator system for his lower over denture. A new set of dentures were made to fit in with the installed locator system, using a ball attachment for the abutment. This secures the dentures in place but also allows for their removal. It should be added that an advantage to Mr H with this treatment, is that an implant retained denture is much smaller than an ordinary denture thus restoring his ability to taste food and thereby enjoy life more.

Sky Implants: Fast and Fixed concept

 

 

Background

Mrs C thought she was too young for dentures. In the past the gaps between her teeth were originally closed by bridges. However, the teeth used to maintain the bridges in place had over time gradually degraded through excess loading and decay under the bridges. Mrs C could only just about eat with her clasp-retained denture.

Treatment

A Treatment Plan for Mrs C was devised using the SKY ‘Fast and Fixed’ system. Six implants in the upper jaw were inserted (known as All-on-six) and in a similar manner four implants were also fixed to her lower jaw (All-on-four) to secure a full set of new teeth on a fixed bridge in JUST 1 DAY! The advantages of using this technique for Mrs C were several:

• Mrs C had new teeth in only one day (No one needs to be aware of the treatment.)
• The function aesthetics for her were maintained right from day one.
• Mrs C avoided a long treatment plan that can extend, using other techniques to several months or possibly years.
• All the initial extractions, implant surgery and fixing of teeth were performed at the same occasion.
• Complex grafting such as sinus grafts (increasing the amount of bone in the upper jaw) or nerve repositioning in the lower jaw or onlay grafting (using material taken from the patient’s own body) was avoided.
• Due to the reduction in treatment time, the cost for Mrs C was significantly lower.

Prior to the day of her surgery, some low-dose X-rays of Mrs C’s jaw were taken, followed by a CT scan. The latter provided our dentist with information regarding her bone quality, position of her nerves and sinuses. On the actual day, the surgery was performed under local anaesthetic, with the implant placement and any extractions taking about 2 hours for each jaw. Later in the day a temporary bridge (full arch fixed prothesis) was attached to the dental implants. This provisional restoration of her teeth meant that no one noticed the treatment. The bridge, although temporary, looked very natural, since our dentist had taken care refining the bite and aesthetics. Before going home Mrs C booked a review appointment with us for a fortnight later. This was to check that all is well and to see if any minor modifications were needed. (After the placement of the implants it is usual to have a period of five to six months to allow for integration and healing with the jaw bone. Then the permanent bridge was made and fitted.)
