By replacing one single tooth and avoiding the conventional bridge approach, the adjacent teeth are preserved. Dental implants come in various sizes of length and width. Since molars typically do most of the work during chewing, using an implant of maximum size is always preferred. By determining the exact jaw dimensions prior to implant surgery, the implant team is able to decide on just the right implant for the tooth to be replaced. Dental CT scan technology is used to plan the implant surgery in a precise manner by using computer assisted planning software (See CT Scan Technology).
Healing time: The time between surgical implant placement and final crown placement is typically shorter on the lower jaw than it is on the upper jaw. This is a result of denser bone in the lower jaw, which allows for faster fusing (osseointegration) of the bone with the implant's outer surface. Lower implant restorations can be completed in less than 10 weeks from surgical implant placement, as compared to at least 16 weeks for an upper back tooth.
If the teeth to be replaced need to be removed, their extraction may be able to be completed at the same time as the dental implant placement. This "one-stage" protocol can be followed when the tooth to be replaced has a single root and is not infected. Molars have at least two roots and usually require a "two-phase" treatment sequence. The two-phase sequence requires that the remaining roots are removed first and bone filled (grafted). The bone graft is allowed to heal for up to 12 weeks before the implant is surgically inserted in the second phase.
Anatomy: Hybridge Treatment Protocols differ between the upper and the lower jaw due to their significant anatomic differences.
Upper Jaw – "Maxilla"
The bone in the area of the upper back teeth is limited by the location of the Maxillary sinus on both sides. Often after tooth loss, there may not be enough remaining bone to place an implant. When additional bone is required, a sinus lift bone graft may be necessary. If this procedure can be performed at the time of the implant surgery, the additional fee is limited to the material costs. The additional waiting time required is usually minimal. If the sinus lift bone graft must be done as a separate surgical procedure, the additional cost of materials to grow the bone is greater, as is the waiting time until the dental implant can be surgically placed (typically 4 months). Treatment Time: 4-12 months
Lower Jaw – "Mandible"
The back teeth area in the lower jaw sits above what is known as the mandibular nerve. As such, care is taken to avoid placing a dental implant too close to the mandibular nerve. CT scans are used to measure its location. This cutting-edge technology allows for pre-surgical computer planning, which minimizes the chance of complication or failure. Treatment Time: 2-6 months
Single Back Tooth
Description: Replacing a Single Back Toothis by far the most common tooth replacement scenario. Molars and pre-molars are usually the first teeth to be lost due to decay and gum disease. Thus, doctors at Hybridge Implant Centers have replaced thousands of Single Back teeth over the last 20 years. As with all aspects of implant dentistry, the time and efficiency of replacing back teeth makes it one of the most predictable dental procedures performed.
Research shows that 80% of chewing is done in the area of the first molar. The replacement of first molars should be seen as a high priority to maintain full function, with both bite and jaw stability. The second molars, on the other hand, are not nearly as important to good function, and in many cases are not replaced unless a patient feels the chewing surface is missed.
Single Front Tooth
Description: It has often been said that replacing a single front tooth can be one of the most challenging forms of tooth replacement. The determining factor is the level of prominence the tooth has in the smile, and the level of expectation that the patient has that the new tooth will look indistinguishable from the natural teeth around it.
Dental implants come in various sizes of length and width. Because front teeth are typically used for tearing food, using an implant of maximum size in this scenario is always preferred. Determining the exact jaw dimensions prior to implant surgery allows the implant team to decide on just the right implant for the tooth to be replaced.
