Zusammenfassung (Synopsis, page 693)

The extraction of teeth or the removal of roots in a modern dental practice is often a traumatic experience for patients. The contribution of The Ögram System establishes with instrumentation and extraction methodology that trauma for tooth removal is minimized. This report of a Clinical Study is the implementation of this System based on 65 tooth removals of 34 patients with varied clinical situations. In not one case was there a post extraction wound healing disorder. The precedence is a non-invasive extraction technique.

Resümee (Summation, page 704)

The Ögram System offers new possibilities for dentists to reduce trauma for procedures of tooth, root, or root fragment removals. This is accomplished by no longer requiring an osteotomy or the need for surgical reflection of gingival tissues and the preservation of the cortical alveolus (for non-impacted removals), through exact technic and the proper manipulation of exact instrumentation for each specific situation. Tooth removal trauma is minimized for each specific situation with reduced extraction times, by application of exact technique and instruments used in the Ögram System, also the elimination of profound hand forces by the practioner, and at the same time reducing stress for the practioner and the patient. With the implementation of The Ögram System, the provision of tooth saving partial hemi-section is far less traumatic. Due to attainable minimizing of trauma in tooth removal using exact instrumentation and easy to apply techniques, adequate alveolar and crestal bone retention will allow for preferable future prosthetics and will also have a special meaning for implants.

Zusammenfassung (Synopsis, page 863)

An important goal in modern dental medicine is the retention of alveolar bone after tooth loss. Therefore the dental arch can provide esthetic and sound clinical results for implants. The goal of this report is to present two different tooth removal possibilities: the standard method for tooth removal and a new extraction method (Ögram) which is a far less invasive technique and uses instruments that are anatomically correct to the tooth's morphology. This clinical will show, that with the Ögram System the operation yields minimal trauma and that bone resorption can be greatly reduced. So that better results for future implants can be better accomplished.

Patienten, Material and Methoden (Patients, Material and Methods, page 864)

At the beginning of 1997 until mid 1998 170 patients had 198 teeth extracted. Patients were only accepted with the understanding that a 3-month post extraction assessment was required of each patient for the control group. Patients that did not return for the 3-month post extraction assessment were not included. The clinical study therefore was based on 166 extractions from 125 patients.

The 62 female and 63 male patients were between the ages of 15 to 87 years old (average age was 49 years old). The selection process for our patients in this study had the following requirements:

- no local or altogether bone disease for either dental arch so that bone loss values could be properly observed;

- no horizontal bone resorption in the apical third of the root;

- no periodontal pockets;

- no loose teeth.

The planned conclusion to this study is to assess the difference between two tooth extraction methods, with the distribution of the patients into two groups:

- Group A encompasses patient treatment with conventional extraction methods.

- Group B represents patients that received the Ögram System extractions.

The patient base for both study groups were categorized and divided into three Classes with relationship of adjoining teeth:

- Class I: The extracted tooth had mesial and distal neighboring teeth.

- Class II: The extracted tooth had mesial or distal a neighboring tooth (one tooth adjoining only).

- Class III: The extracted tooth had mesial or distal no neighboring tooth

Ergebnisse (Results, page 866, last paragraph)

The results of alveolar resorption 3 months post extraction by the conventional extraction and extractions with the Ögram System shows an average value loss of 2.6 mm [plus or minus 1.48 mm] in Group A and 0.2 mm [plus or minus 0.45 mm] in Group B (Table 1). The minimum value of bone resorption in both Group A and Group B showed 0.0 mm., the maximum value exhibited a significant difference between Group A with 8 mm bone loss, and Group B with 1 mm bone loss. The average of the T-Test proves an important significant statistical difference (p=4.73E-24) and can be confirmed between both Groups.

Diskussion (Discussion, page 867)

It is commonly known, that with tooth removal almost always more or less alveolar bone is resorbed, where as with less invasive extraction technique alveolar resorption can be reduced and even eliminated. The regeneration of bone in the upper arch is slower than the lower arch. While the anatomical change in the lower arch requires a wait of 2 months, one must wait 3 months for the upper arch before continuing with dental treatment.

The here described study of the new tooth removal system shows after our clinical experiences that this new surgery possibility offers far greater results. The observation using both tooth removal possibilities clearly shows the advantage in bone retention. The retention in bone clearly shows for better overall implant results. The new method can for this reason be highly recommended.

The results of this study show, that patient bone loss or bone resorption after tooth removal by traditional methods is substantially higher, than compared with the Ögram System. The presented surgical methods of noninvasive and greater bone retention possibilities clearly shows that this new removal system offers the best prognoses for future prosthetic procedures or implant prosthetic treatments. With complex tooth removals (non-impacted) the Ögram technique is an absolute must as it reduces the need of an osteotomy by 30%!

The Ögram System^TM

THE RESULT

This innovative new and advanced Exodontia technique system:

• Protects the cortical shell, periosteum, and surrounding tissues

• Eliminates the use of flaps

• Limits trauma and bone loss (Eliminated in 86% of non-impacted teeth based on 33 dentists combined statistics, compared to 11% with conventional extractions)

HISTORY

The Ögram System team of professionals from many scientific, medical, dental and medical engineering disciplines in the U.S. and Europe evaluated tooth extraction techniques commonly used in current dentistry. They determined that current exodontia technique is based on 19th century principles that use excessive strength and force and result in a high degree of surrounding tissue trauma. Most dental schools in the U.S. and Europe still teach students exodontia technique with century old instrument patterns.

Histological assessments of soft and hard tissues surrounding teeth was investigated initially to determine which tissues should be preserved to avoid permanent defects and complicate potential implant surgery. Periosteum and cortical bone were deemed to be the key tissues for preservation. Trauma to these two tissues was found to be the reason for post tooth extraction bone loss. The motion equations were scripted for the technique and finally the instrumentation was chosen for optimal technique delivery. After six years of development with Gunnar Philipp as team leader and lead surgical designer, the team engineered the new exodontia technology known as "The Ögram System".

THE TECHNIQUE

The Ögram System is an easy system to learn and impliment for simple and complex tooth removal that protects the cortical shell, alveolus, periosteum, and surrounding bone and tissues - all imperative to today’s implant practices. The Ögram System allows a dentist to remove almost all difficult, non-impacted teeth in 10 minutes or less of technique time with high predictability and without the need of reflecting a flap, trenching, removal of facial cortical bone or excessive instrument forces. No other method currently accomplishes these goals. Simply put, there is no other exodontia method that carries these distinctions offering so much to patients and dentists.

THE COURSE

Learn the step-by-step protocol of the Ögram System from team leader, Gunnar Philipp in this course, that has been attended by more than 50,000 dentists in the U.S. and Europe. The Ögram System has been implemented in dental schools in Germany, France, Austria, Switzerland, United States and is expanding to other countries.

The Ögram System offers new possibilities for dentistry and shares very little with traditional technique or logic. About 85% to 90% of the technology will be new to the dental profession. You owe it to your practice and your patients to learn this quick, simple, yet advanced system of gentle tooth extraction that allows you to preserve local anatomy.
