Open Healing: A Minimally Invasive Protocol with Flapless Ridge Preservation in Implant Patients

Collagen-Based Medical Devices for Regenerative Medicine and Tissue Engineering

Assisted reproductive technologies are key to solving the problems of aging and organ defects. Collagen is compatible with living tissues and has many different chemical properties; it has great potential for use in reproductive medicine and the engineering of reproductive tissues. It is a natural substance that has been used a lot in science and medicine. Collagen is a substance that can be obtained from many different animals. It can be made naturally or created using scientific methods. Using pure collagen has some drawbacks regarding its physical and chemical characteristics. Because of this, when collagen is processed in various ways, it can better meet the specific needs as a material for repairing tissues. In simpler terms, collagen can be used to help regenerate bones, cartilage, and skin. It can also be used in cardiovascular repair and other areas. There are different ways to process collagen, such as cross-linking it, making it more structured, adding minerals to it, or using it as a carrier for other substances. All of these methods help advance the field of tissue engineering. This review summarizes and discusses the current progress of collagen-based materials for reproductive medicine.

Clinical Effect and Aesthetic Evaluation of Minimally Invasive Implant Therapy

Objective

To explore the clinical effect and aesthetic evaluation of minimally invasive implant in the treatment of dentition defect.

Methods

From April 2020 to May 2021, 60 patients who received implant restoration were collected as the research objects. Randomly divided into minimally invasive surgery group (30 patients) and routine surgery group (30 patients). The postoperative antibiotic use time, pain disappearance time, swelling degree, and pain degree of the two groups were compared. Follow-up for one year, record and compare the success rate of implants and aesthetic evaluation of restoration between the two groups. The evaluation of patients' satisfaction with restoration was collected and compared.

Results

The operation time and antibiotic use time of patients in minimally invasive surgery group were significantly shorter than those in conventional surgery group, and the swelling degree rating was significantly better than that in conventional surgery group, with statistical significance (P < 0.05). The number of patients with no pain (0 degree) and mild pain (degree) in minimally invasive surgery group was significantly higher than that in routine surgery group, and the difference was statistically significant (P < 0.05). One year after the repair, the success rate of implants in minimally invasive surgery group was 100.00% compared with that in routine surgery group (93.33%), and the difference was not statistically significant (P > 0.05). The aesthetic effect scores of patients in minimally invasive surgery group were higher than those in routine surgery group in seven items: proximal gingival papilla, distal gingival papilla, labial gingival margin curvature, labial gingival margin height, root convexity, soft tissue color, and soft tissue texture, with statistical significance (P < 0.05). The satisfaction scores of the patients in minimally invasive surgery group in chewing function, comfort, aesthetics, retention function, and language function were higher than those in conventional surgery group, and the differences were statistically significant (P < 0.05).

Conclusion

Minimally invasive implant can achieve the same effect as conventional implant, and it has the advantages of lower postoperative swelling, shorter pain time, better aesthetic effect, and higher satisfaction after restoration.
