    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
