Study Notes
Complications in Dental Implant Surgery
- Accidents occur during surgery, while complications appear after surgery and can be classified as early-stage or late-stage complications
- Early-stage complications occur in the immediate postoperative period, interfering with healing
- Late-stage complications arise during the process of osseointegration
- Iatrogenic acts are regarded as accidents, complications or failures caused by a deficient praxis of the professional
Local Complications in Dental Implant Surgery
- Infection
- Edema
- Ecchymoses and hematomas
- Emphysema
- Bleeding
- Flap dehiscence
- Sensory disorders
- Perforation of the mucoperiosteum
- Maxillary sinusitis
- Mandibular fractures
- Failed osseointegration
- Bony defects
- Periapical implant lesions
Classification of Complications (Carranza)
Surgical Complications
- Hemorrhage and hematoma
- Neurosensory disturbances
- Damage to adjacent teeth
Biologic Complications
- Inflammation
- Dehiscence and recession
- Periimplantitis and bone loss
- Implant loss or failure
- Screw loosening and fracture
- Implant fracture
- Fracture of restorative
Technical or Mechanical Complications
- Materials
- Esthetic complications
- Phonetic complications
Esthetic and Phonetic Complications
- Bleeding
- Phonetic complications
Causes of Bleeding
- Lesions in sublingual, lingual, perimandibular, or submaxillary artery
- Surgeries in the lower and anterior area of totally edentulous patients with a deficit in bone quality and quantity
- Lack of asepsis during sinus augmentation
Management of Bleeding
- Preoperative evaluation of sinus clearance-related factors
- Postsurgery: nasal decongestant and topical corticosteroid to prevent ostium obstruction
- Perioperative antibiotic prophylaxis
Failed Osseointegration
- Defined as a direct structural and functional connection between ordered living bone and the surface of a load-carrying implant
- Factors affecting osseointegration:
- Implant failure
- Surface roughness
- Surface purity and sterility
- Fit discrepancies
- Intra-oral exposure time
- Mechanical overloading
- Premature loading
- Traumatic occlusion due to inadequate restorations
- Patient local factors (oral hygiene, gingivitis, bone quantity/quality, adjacent infection/inflammation, presence of natural teeth, periodontal status of natural teeth)
- Patient systemic factors (vascular integrity, smoking, alcoholism, predisposition to infection)
Phonetic Complications
- Unusual palatal contours (restricted or narrow palatal space)
- Spaces under and around the superstructure of the implant
- Management: implant-assisted maxillary overdenture
Maxillary Sinusitis
- Contamination of the maxillary sinus with oral or nasal pathogens
- Ostial obstruction caused by postoperative swelling of the maxillary mucosa
- Non-vital bony fragments floating freely in the maxillary sinus
- Risk factors: age, obesity, steroid therapy, malnutrition, metabolic disease, chemotherapy/radiotherapy, hypersensitivity to implant components
- Surgical technique/environment
- Surgical trauma
- Overheating (use of handpiece)
- Perioperative bacterial contamination
