FIADAN dental implants are an implant system widely used in the field of modern oral restoration. Their design focuses on bone integration stability and restoration aesthetics, and can provide patients with a more ideal restoration plan after tooth loss. The dental implant surgery process is not only a stacking of mechanical operations, but also a combination of precision surgery and biological principles . This article combines clinical practice with related research to systematically explain the standard surgical process of FIADAN dental implants and its precautions, in order to provide clinical workers with technical points for reference.
Preoperative patient evaluation
Preoperative evaluation is the basis for successful implant treatment . Clinicians need to conduct a comprehensive examination from the following aspects:
Medical history collection : including systemic health conditions (such as diabetes, cardiovascular disease, osteoporosis, etc.) and medication history. Some systemic diseases may affect bone healing or increase surgical risks.
Oral examination : It is necessary to evaluate the conditions of soft and hard tissues, such as alveolar bone volume, height, width, mucosal thickness, periodontal health, etc.
Imaging examination : Cone beam CT (CBCT) can accurately measure the three-dimensional morphology of the alveolar bone and determine the bone density and the position of adjacent anatomical structures (such as the inferior alveolar nerve and maxillary sinus).
Model analysis : Diagnostic wax-up is made through oral scanning or traditional impression to plan the implant position and upper restoration design.
After the preoperative evaluation is completed, the physician should develop an individualized treatment plan based on the patient's specific situation to determine whether bone grafting, maxillary sinus lift or other auxiliary procedures are needed.
Anesthesia and preoperative preparation
If conditions permit, local infiltration anesthesia is usually used. The surgical area should be strictly disinfected. Patients can use antibacterial mouthwash to reduce oral flora before surgery. If the patient is nervous, mild sedatives may be given as appropriate, but attention should be paid to the patient's general condition and drug contraindications.
Incision and flap
When the operation officially begins, the doctor makes a ridge incision or a palatal incision at the alveolar ridge , combined with a vertical release incision. During the flap opening process, the mucosa must be kept intact to avoid tearing to facilitate postoperative healing.
Key Takeaways:
①. The incision should avoid important anatomical structures.
② The flap must be wide enough to expose the bone surface to facilitate subsequent operations.
③. Maintaining sufficient keratinized mucosa is conducive to the health of the soft tissue around the implant.
Implantation nest preparation
Implant socket preparation is the core link that affects implant stability. The preparation sequence is usually: positioning with a fixed-point drill → drilling with a guide drill → gradually expanding to the designed diameter and depth.
Preparation principles include:
①. Strictly control the drilling speed and pressure to prevent overheating of bone tissue. The recommended drilling speed is ≤800 rpm.
②. Use sufficient saline solution for cooling.
③. Follow the drill tools and standard operation provided by the Fei Yadan system to ensure that the socket shape matches the implant.
④. In areas with relatively porous bones, the diameter of the implant socket can be appropriately reduced to improve initial stability.
If there is insufficient bone during the operation, bone transplantation or the use of bone substitute materials should be considered. After preparation, a probe can be used to detect the integrity of the socket wall and flush out the bone chips.
Implant placement
Gently screw the Feyardan implant into the implant socket, avoiding excessive torque during the process. The ideal initial stabilizing torque is generally between 25 and 35 Ncm . If the torque is too low, it should be evaluated whether a larger diameter or a different design of implant is needed.
The implant depth needs to refer to the bone ridge height and the relationship with adjacent teeth. In some cases, the implant can be placed slightly below the bone ridge according to the restoration plan to facilitate later soft tissue shaping.
Restorative abutment installation or closure screw placement
If the bone quality is good and initial stability is adequate, immediate restoration with the installation of a healing abutment can be considered, or if delayed restoration is required, closure screws can be placed and the soft tissue can be sutured.
Suturing and postoperative care
The soft tissue coverage should have low tension and good edge apposition. After suturing, check that there is no obvious bleeding in the surgical area. The patient should follow the doctor's instructions after surgery:
①. Apply local cold compress to reduce swelling.
②. Use antibacterial drugs appropriately.
③. Avoid gargling vigorously or eating overheated or hard food.
④. Follow up regularly and observe the healing condition.
Healing period and upper repair
A bone integration period of 3 to 6 months is usually required after surgery , during which time the soft tissue condition needs to be monitored and the bone integration status needs to be evaluated by X-ray.
After the healing period, the upper repair phase begins:
1. Second-stage surgery or removal of the closure screw and installation of a healing abutment to reshape the soft tissue.
2. Make impressions, either digital scanning or traditional impressions.
3. Design restorations, including single crowns, bridges or complete dentures.
4. Install the restoration and make occlusal adjustments.
The Feyadan system has rich restorative options to meet the needs of different patients. The precise production and correct installation of the restoration are the key to successful implantation .
Complications and treatment
The Feyadan implant system performs well in clinical applications, but the following complications still need to be paid attention to:
Insufficient initial stability of the implant : Restoration can be postponed or a wider diameter implant can be used.
Bone resorption or bone defect : Assess bone quality before surgery and perform bone augmentation if necessary.
Soft tissue hyperplasia or atrophy : Perform delicate operations during surgery and try to preserve the keratinized mucosa.
Peri-implantitis : emphasize the patient's oral hygiene management after surgery and regular check-ups.
Tip: Fei Yadan dental implant surgery process is systematic and standardized, from preoperative evaluation to final restoration, all are closely linked. Clinicians should strictly follow the principles of biology and mechanics during the operation, paying attention to the accuracy of implant placement, while also taking into account soft tissue aesthetics and long-term maintenance. With the help of scientific design and standardized operation, it can provide patients with more ideal restoration effects in most clinical situations.
