This presentation, "Complications during Tooth Extraction and Surgical Tooth Removal (Part 1)," provides comprehensive guidance for dental practitioners on preventing and managing intra- and post-operative complications. The lecture stresses the critical importance of pre-operative patient assessment, focusing on cardiovascular disease, coagulation disorders (hereditary and acquired), chronic liver disease, and endocrinological issues like diabetes mellitus, which can impact hemostasis and wound healing. Key procedural steps include verifying the extraction indication, developing an overall treatment plan (e.g., bridge, implant), and educating patients on alternatives (e.g., endodontic therapy). Specific complications discussed include soft tissue injuries, nerve lesions, jaw fractures, and the management of root remnants and or-antral fistulas (maxillary sinus openings). Detailed protocols are provided for handling extracted healthy teeth (replantation and splinting) and closing or-antral fistulas using various surgical flap techniques (Rehrmann's, Axenfeld's, Kazanjian's).
Complications in Tooth Extraction and Surgical Removal (Part 1)
0:36 Pre-Operative Assessment: Prioritize knowing the patient's medical history to avoid complications, especially concerning:
Cardiovascular diseases (chronic heart disease, heart failure, thrombosis). Referral to a general practitioner is often required.
Chronic liver disease (risk of impaired hemostasis/blood clotting due to reduced factor production).
Endocrinological diseases (Diabetes Mellitus Type 1 can cause wound healing problems due to small vessel issues; antibiotics may be necessary for long-standing cases).
Hyperthyroidism (refer if resting heart rate is over 90 bpm).
3:15 Coagulation Disorders: Differentiate between hereditary (Hemophilia A/B) and acquired (anticoagulants, aspirin, Macumar). Small extractions are manageable if factor levels are above 1% or if the patient is on low-dose anticoagulants (e.g., 100 mg aspirin).
4:17 Radiotherapy Risk: Patients who have received full tumor-dose radiotherapy to the jaw risk osteoradionecrosis; extraction wounds must be closed extremely well.
5:17 Verification of Indication: The operating surgeon is legally responsible for the extraction decision, regardless of the referral. Must ensure the indication is correct and establish an overall treatment concept (e.g., future crown, implant, bridge).
6:42 Alternatives to Extraction: Must inform the patient about viable alternatives, including endodontic therapy, apicectomies (keeping teeth for decades), hemisections (lower molars), and root amputations (upper molars).
8:41 Radiological Diagnostics: The orthopantomogram (OPG) provides a necessary overview of teeth and bone. CBCT (Cone-Beam CT) offers superior 3D detail, especially for nerve-root relationship, but exposure should be limited to the zone of interest.
12:10 General Risks & Patient Information: Essential risks to inform the patient about: primary bleeding (immediate) and secondary bleeding (days later, often due to manipulation/sucking on the alveolus). Advise patients not to drive or operate difficult machinery for at least one hour post-op.
Nerve Lesion: Primarily the mandibular nerve; use CBCT to evaluate proximity, especially for wisdom teeth.
Antrofistella: Opening of the maxillary sinus due to close anatomical relationship.
Jaw Fracture: Possible, especially with deep mandibular wisdom teeth; prevent by dividing the tooth rather than using heavy leveraging (18:15).
18:35 Intraoperative Soft Tissue Injury: Avoid grabbing gums with forceps. Be cautious of thermal injury (e.g., from a hot handpiece) on numb tissue.
26:12 Root/Tooth Fractures: Often caused by deep caries, crowned teeth, pin crowns, heavily curved roots, or root ankylosis (common in older patients). A "crackling noise" followed by the tooth removing "too easily" (29:30) is suspicious of a root fracture.
33:01 Management of Root Remnants: Surgical removal is usually safest. If a very small, non-inflamed root tip is deeply buried (e.g., small piece of a wisdom tooth root), it may be left in situ as a rare exception, with strict follow-up X-rays.
35:40 Extraction of the Wrong Tooth: If this happens, immediately inform the patient and document the event. Replant the extracted healthy tooth and stabilize it with a splint (e.g., orthodontic wire/composite, acrylic cap, or titanium trauma splint) for 2β3 weeks. Adult patients typically require endodontic therapy 10 days/2 weeks later.
41:02 Maxillary Sinus Opening (OAC): An anatomical complication. Confirm using a nasal blow test (if the sinus is healthy/not inflamed) or by careful probing.
43:16 OAC Closure Protocol: Must be closed surgically within 24 hours if the sinus is healthy. If inflamed, rinse with saline/chamomile first. Post-op care: no smoking, no nose blowing for two weeks, and use nasal drops.
45:30 OAC Surgical Closure Techniques: Common methods include the Rehrmann trapezoidal flap (requiring periosteum division and epithelial removal) and the Kazanjian bridge flap (useful for edentulous patients).
49:02 Root Remnants in the Maxillary Sinus: Requires confirmation, often via CBCT, to ensure the remnant is inside the sinus and not merely projected into the soft tissue.
51:43 Sinus Opening for Removal: Removal requires surgically opening the sinus (osteoplastic approach, often via the frontal wall), creating a bone window (e.g., with a piezo instrument), and then replacing the bone lid with absorbable sutures.
