Suturing is a critical component of implant surgery, ensuring wound closure, protection of surgical sites, and promotion of optimal healing. The choice of suture materials and suturing techniques can directly influence the outcome of the procedure, from the prevention of infection to the minimisation of post-operative complications. At Dazzle Dental Clinic, precision suturing is an integral part of every dental implant, zygomatic implant, and All-on-4 surgery.
Types of Suture Materials Used in Implant Surgery
Resorbable sutures dissolve naturally and are used in most implant surgery cases. The most commonly used resorbable materials at Dazzle are polyglycolic acid (PGA) and polyglactin (Vicryl). These break down through hydrolysis over 60–90 days, eliminating the need for suture removal in most cases. Resorbable sutures are preferred for flap closures where the tissue is well-approximated and healing is expected to proceed without tension.
Non-resorbable sutures (typically 4-0 or 5-0 polypropylene or nylon) are used in specific situations: where precise and prolonged tension-free wound closure is required; at papilla-preservation incision sites in the aesthetic zone where precise suture removal at 7–10 days allows reassessment of tissue adaptation; and for guided bone regeneration membrane closures where prolonged stability is critical.
Key Suturing Techniques
Simple interrupted sutures: The standard technique for most implant wound closures. Each suture is independent, reducing the risk of complete dehiscence if a single suture fails. Used throughout the flap closure in routine implant cases.
Horizontal mattress sutures: Distribute tension over a wider tissue area and evert the wound margins slightly, promoting primary healing. Particularly useful at papilla-preservation incision sites in the anterior zone, where precise tissue adaptation is critical to the aesthetic outcome.
Figure-of-eight sutures: Used to close extraction sockets after tooth removal and immediate implant placement. This technique maintains the clot and PRF membrane in the socket while the gingival margins begin to close.
Vertical mattress sutures: Reserved for sites requiring significant tissue eversion and tension-free closure. Used in conjunction with advanced GBR procedures or connective tissue graft placements.
Suture Selection in Complex Cases
For full-arch immediate loading cases (All-on-4 and All-on-6), the suture approach is mapped out as part of the pre-surgical plan. The extent of flap elevation, the number of implants, and any concurrent bone or graft procedures determine the suturing sequence. In zygomatic implant cases, periosteal sutures are placed first to re-approximate the elevated periosteum before the mucosal flap is closed in layers.
For bone augmentation cases using resorbable membranes, the flap is designed to close without tension over the membrane. If primary closure cannot be achieved tension-free, releasing incisions are made at the base of the flap, and horizontal mattress sutures are used to maintain closure over the critical healing period.
FAQs
Q1: Will I need to come back to have sutures removed?
For most implant cases at Dazzle, resorbable sutures are used and do not require removal. Where non-resorbable sutures are placed (anterior aesthetic zone, GBR closures), a removal appointment is scheduled at 7–10 days.
Q2: Is suture dehiscence (opening) a serious problem?
Minor wound opening at a suture site is common and usually heals by secondary intention without compromising the implant outcome. Significant dehiscence over a bone graft membrane is more serious and requires clinical reassessment to ensure the membrane is not exposed and contaminated.
Q3: What suture material is used for zygomatic implant cases?
At Dazzle, zygomatic implant flap closures use a layered approach: absorbable periosteal sutures (Vicryl 4-0) for the deep layer, followed by absorbable or non-resorbable sutures at the mucosal surface depending on the extent of the procedure and the surgeon's assessment of wound tension.
