Immediate implantation following tooth extraction. A clinical case study.

Dr. Winfried Walzer

The placement of the implant in a post-extraction bed is a technique, that has been developed especially within the last 10 years.

For immediate implant placement we have the option for an incision and detachment or for a flapless surgery. Generally there is a tendency for a flapless procedure when there is adequately keratinized gingival and a correctly aligned gingival margin.

Since primary stability is more difficult to achieve in immediate implant placement the aspect of choosing the ideal implant body becomes more important.

Case Description: A 53 year old patient presents himself with a reduced dentition in the mandible.
To give the patient a fixed restoration, five implants have been inserted – two in the left, and three in the right mandible.

The implant of choice here was a BL (bone level) Morse conical connection Implant D4,3/L13mm from C-TECH. The shape, angle and depth of the threads are specifically conceived to increase contact surface with the bone and improve primary stability. The root form anatomical design with a slight taper at the implant collar is the ideal design to achieve good bone contact and reduce the gap between implant and bone at the alveolar crest.

The second stage surgery is minimal invasive through the internal hex connection. The shape of the healing abutment minimizes the trauma on the soft tissue, since we do not expose the implant sholder by elevating a flap. The Morsel locking tapered internal conical hex connection of the BL Implant comprises two proven elements in implant prosthetics; a tapered Morse conical connection with a hex at the base. The conical taper provides a cold welding seal which locks the abutment into its final seated position. The hex at the base of the implant provides an optimal positioning index. The combination of taper and hex deliver a high level of prosthetic precision while ensuring against abutment loosening.

Summary: There is not enough reliable evidence proving higher success of immediate implant placement over delayed implantation. Post-extraction implants have survival rates similar to implants placed in healed sites.

If primary stability is achieved, immediate implant placement following tooth extraction can be a viable alternative to delayed placement.
The benefit of immediate implant placement for the patient is obvious:
First of all it reduces the treatment time and if immediate loading is an option, a temporary removable denture can be avoided.

Minimal invasive, cost effective alternative

Prof. Dr. Torsten Mundt Center for Dental, Oral and Maxillofacial Surgery Greifswald Polyclinic for dental prosthetics and materials science University Medical Center

The 4 year survival rates of mini dental implants used in the stabilization of the full prosthesis stand at 95% success or higher. Will mini dental implants establish themselves as a viable therapy for compromised bone volume? Interest in mini dental implants is increasing. Research and studies on MDIs is also increasing, but despite this trend skepticism remains.

Mini dental implants? Sure!

Dr. Kai D. Haschemian

Especially in atrophied mandibles, where conventional diameter implants meet their limits, mini dental implants can be a sensible solution.
This is also true in patients, where an invasive procedure can pose medical risks. Thanks to the diameters of mini dental implants, which are less than
3 mm, cases where the mandible is very thin, the MDIs can be placed with a minimal invasive procedure that often does not require bone augmentation.
The most common indication for the mini dental implants in our practice is for the stabilization of the full denture in the lower jaw. Edentulism is a disability that may even result in the higher mortality of the patient. A prosthesis, which is solely supported by the gingival tissue does not provide an adequate replacement of the missing dentition: especially in the case of the atrophied jaw where the retention is especially low. This compromised situation can result in the avoidance of social situations as well as malnutrition due to food restrictions. Through implant therapy, it is possible to stabilize the prosthesis and thus substantially increase the patient’s quality of life.
Unfortunately, a conventional implant therapy does not come into question for many patients. Especially with senior citizens with medical risk factors there would be large concerns about a heavy surgical procedure where a bone augmentation might be required. Additionally the cost factor plays a large role with many patients. Here mini dental implants offer a cost effective and minimal invasive alternative that is acceptable for many patients.

MINIS (Mini Dental Implant): ACCEPTANCE IS GROWING

Dr. Norbert Enkling

Although accepted in the dental practice, mini dental implant had long been seen with skepticism. But in the last years mini dental implants have attracted the attention of academics and researchers and have been followed up with studies from many different universities around the world. Whereas there were initial fears about the survival rates and risks of fractures on mini implants, the studies have shown that the survival rates of mini dental implants are actually quite similar to those of conventional implants. These studies, till now have mostly addressed the main indication of the mini dental implants, that of stabilizing the full prosthesis in the edentulous mandible.

Mini Dental Implants Used as Strategic Support for the Retention of Partial Dentures

Dr. Friedhelm Heinemann University of Greifswald · Department of Prosthodontics, Geriatric Dentistry and Medical Materials Science, Dr. Christoph Bourauel University of Bonn | Uni Bonn · Zentrum für Zahn-, Mund,- und Kieferheilkunde, Dr. Istabrak Hasan, M.Sc.

Partial dentures supported on natural teeth are a standards in dentistry and are used on a significant percentage in the prosthetic cases in the German population. In the future, with the improvement of dental hygiene in the population there will be less total edentulism but instead there will be an increase in the cases of partial edentulism and consequently there will be an increase in partial bridges.
Mini dental implants offer a viable alternative to natural tooth and conventional implant supported partial bridges. When using mini dental implants in this role it is important that certain guidelines are followed in order to achieve long term success

Systematic Approach to the Insertion of Mini Dental Implants as Additional Support

Dr. Jochen Hilgert

Mini implants have been available in Germany for over ten years.
Mini dental implants have been approved for long term use and now are used in the millions.
In my practice in Drensteinfurt, i have been using mini dental implants, MDIs, since 2001 in cases of the stabilization of the full prosthesis. and since 2003 I have used mini dental implants for the support of partial dentures.
After the indication of stabilization of the full prosthesis, surely the second biggest
potential for mini dental implants lies in the support of partial dentures.

Mini Dental Implants for Stabilisation of the Partial Prosthesis

Dr. Winfried Walzer

From the point of view of esthetics and cost, dentures are seen as acceptable but when it comes to functionality and comfort though, the solutions are quite limited. The reason for this may be that for many patients, the high cost of treatment as well as the trauma involved make it impossible. Now, thanks to the clinically proven worthiness of mini dental implants, it is possible to treat a larger percentage of patients in a quick and cost effective way that provides a functional solution with a secure retention of the prosthesis. The MDI, mini dental implants with diameters of 1,8 / 2,4 and 2,9 through a minimal invasive protocol are able to stabilize full and partial prosthesis.

Multiple abutments with mini-implants
Extended indication for the stabilization of partial dentures

Dr. Jochen Hilgert

Since their introduction into the German market in 2001, MDIs, mini dental implants have proven themselves as  a viable solution for the stabilization of the full prosthesis. But following his presentation to the 2nd MDI user symposium in 2011, Dr. Jochen Hilgert, has proven that based on clinical studies,  MDI is also a  real  solution to the stabilization of the partial prosthesis. Dr Hilgert presented a statistical analysis of the study covering his eight years and 525 mini dental implants. Of the 525 mini dental implants that he set, 75% were in combination with telescopes prosthesis and only 20% of the MDIs were used for stabilizing the full prosthesis.
