The Straumann® Zygomatic implant: 2-year clinical results, Dr Carlos Aparicio

Summary of "The Straumann® Zygomatic implant: 2-year clinical results, Dr Carlos Aparicio"

Short Summary:

This presentation by Dr. Carlos Aparicio focuses on the Straumann® Zygomatic implant, a specialized type of dental implant used in cases of severe maxillary bone loss. Dr. Aparicio shares his two-year clinical results using this implant system, emphasizing the importance of specific criteria for evaluating its success. He highlights the unique characteristics of Zygomatic implants, including their length, anchoring positions, and biomechanics, which necessitate distinct evaluation methods compared to regular implants. The presentation details the "A-O-N-E" criteria for evaluating Zygomatic implant success, encompassing prosthetic offset, peri-implant inflammation, and implant stability. Dr. Aparicio also discusses the importance of considering Reno-sinus associated pathology and presents his clinical findings, demonstrating the effectiveness of the Zygomatic implant system in achieving predictable results and preventing complications.

Detailed Summary:

1. Introduction and Context:

Dr. Aparicio introduces himself and his work at the Hepler Ball Clinic in Barcelona, Spain, specializing in Zygomatic implants.
He emphasizes the need for specific criteria to evaluate Zygomatic implant success due to their unique characteristics compared to regular implants.
He mentions the "A-O-N-E" criteria developed with colleagues to assess Zygomatic implant success, focusing on prosthetic offset, peri-implant inflammation, and implant stability.

2. Zygomatic Implants: Unique Characteristics and Evaluation Criteria:

Dr. Aparicio explains that Zygomatic implants are used in cases of severe maxillary bone loss, requiring longer implants anchored in different positions.
He highlights the need for specific criteria to evaluate Zygomatic implants due to their unique biomechanics and potential complications.
He introduces the "A-O-N-E" criteria:
- Prosthetic Offset (O): Evaluates the final positioning of the prosthetic solution, considering its location relative to the implant head.
- Peri-implant Inflammation (N): Assesses the condition of the soft tissue surrounding the implant neck, looking for signs of inflammation or instability.
- Stability (E): Evaluates the implant's stability, considering potential movement due to the soft bone in which it is anchored.

3. Clinical Study and Results:

Dr. Aparicio describes a cohort study involving 20 patients with a total of 59 Zygomatic implants, followed for 36 months.
He details the inclusion and exclusion criteria for the study, emphasizing the acceptance of patients with chronic signs of Reno-sinusitis.
He presents the results:
- Prosthetic Offset: 15 patients achieved success grade 1, with minimal distance between the implant head and the crest.
- Reno-sinus Associated Pathology: 15 patients achieved success grade 1, with no signs of opacification in the sinuses. 4 patients showed improved sinus status after treatment.
- Peri-implant Soft Tissue Inflammation: 53 implants showed no signs of recession or inflammation. One patient experienced minor recession but no inflammation.
- Stability: 52 implants were stable. One implant showed minor movement but no rotation or pain.

4. Conclusion and Recommendations:

Dr. Aparicio concludes that the Zygomatic implant system, when used with specific surgical techniques and patient-specific tools, provides predictable results and helps prevent complications.
He emphasizes the importance of using the "A-O-N-E" criteria for evaluating Zygomatic implant success.

Notable Quotes:

"When dealing with Zygomatic implants, we are dealing with different totalities. They are called implants, but they are totally different from regular ones."
"There is a tendency to use dental parameters in order to evaluate implants, and there is the tendency to evaluate a regular implant in the same manner as a Zygomatic one, or vice versa. This is not possible."
"We have predictable results and we were able to prevent complications."
