What can go wrong in dental implants | Complication of Dental Implants
The document outlines the potential complications associated with dental implants, including infection, nerve injury, failed osseointegration, and sinus perforation. It emphasizes the importance of proper planning and technique to avoid these issues, such as ensuring correct angulation and depth during placement. Additionally, it discusses the risks of inadequately managed post-operative care and the necessity of thorough understanding of the anatomical area involved.

- 1. WHAT CAN GOWRONG WITH DENTAL IMPLANTS?
- 3. COMPLICATIONS DURING AFTER Failure inplacement Infection Implant breakage Failed Osseointegration Nerve Injury Loose dental implants Sinus perforation Nerve damage Fracture of bone Maxillary sinusitis Bleeding Infection Aspiration Failed Osseointegration
- 4. FAILURE IN DENTALPLACEMENT THIS MAY BE DUE TO – Improper angulation Poor spaced implants Inadequate bone and tissue coverage for implant .
- 5. This may leadto certain problems. Therefore, for a successful dental implant proper axis, depth, and angle needs to be assured. Aesthetic problems Chewing issues Inability to maintain hygiene Difficulty in making restorations
- 6. FRACTURE OF DENTALIMPLANTS This may be due to overloading of implants. May be due to defect in Implant design Implants with smaller diameter are more prone to fracture. Tightening of implants more than the recommended torque.
- 7. SINUS PERFORATION – Thesinus membrane serves as a biological barrier from the oral cavity protecting the sinus from infection. – If sinus lining is in proximation with the dental implant, during implant insertion or tapping the sinus lining may perforate and the implant may go inside the sinus. – If it happens the immediate removal of the implant lodged in the maxillary sinus has to be done otherwise maxillary sinusitis or foreign body reaction may occur.
- 9. NERVE INJURY – Nervesmost commonly affected – inferior alveolar nerve, infraorbital nerve, mental nerve. – Nerve damage can occur either during implant placement or during injecting anesthesia , while raising a flap.
- 10. Three types ofnerve injury occurs : 1. Neurapraxia - There is no loss of continuity of the nerve; it has been stretched or has undergone blunt trauma. The paresthesia will subside, and feeling will return in days to weeks. 2. Axonotmesis - Nerve is damaged but not severed; sensation returns within 2 to 6 months. 3. Neurotmesis - Severed nerve; poor prognosis for resolution of paresthesia.
- 12. INTRA-OPERATIVE BLEEDING – Inpatients who already have prolonged bleeding time like diabetic patients, patient on oral anti- coagulants, bleeding disorders – Injury to inferior alveolar canal during drilling, tapping of implant when the implant is in close proximity to the canal. – control of the hemorrhage can be ensured by compressing the area with the implant or an abutment.
- 13.
- 14. FRACTURE OF BONE –Although it is more common in atrophic mandibles as they are associated with diminished blood supply. – May occur during implant insertion or during tightening of implants when adequate mandibular support is not provided. – Radiological examination should be thoroughly evaluated for height and labial-lingual width of mandible.
- 15. ASPIRATION Instruments like screwdriver , healing caps, abutments are to be carried into their surgical site with extreme precaution because if they slip there are chances that patient might apirate/ swallow them and it will be a case of extreme emergency as airway patency can get compromised and these patient require immediate hospitalization.
- 16. LOOSE DENTAL IMPLANTS •The normal healing period of an implant is 3-6 months during which osseointegration occurs. If the implant is loose, it means it has lost integration with bone and is no longer in contact with it.
- 17. It may bedue to many reasons Infection post- surgery Inadequate amount of bone available Micro-motion during loading the implant Poor surgical technique during placement Over preparation of the site Traumatic surgery Smoking after the procedure
- 18. PERI- IMPLANTITIS • Itis the inflammatory change that takes place in the soft and hard tissues surrounding an osseointegrated implant.
- 20. • The causesmay be : Contamination of implant via accidental contact with the implants or indirectly from gloves or instruments. Improper soft tissue closure can lead to bacterial contamination around the bone resulting in destruction of the tissues surrounding the implant. Unequal occlusal load distribution, which may lead to loosening of the implant and chances of infection in the surrounding area increases. Patient unable to maintain oral hygiene. If a patient is chronic smoker or alcohol consumer.
- 21. POST – OPERATIVEBLEEDING – Laceration of tissues caused by tight or sharp suture material or by incorrect suturing technique – Masticatory trauma – Secondary hemorrhage can occur due to loosening of sutures.
- 22. MAXILLARY SINUSITIS – Closeapproximation of Sinus to the dental implants and wound dehiscence in that area can lead to bacterial contamination and inflammation of maxillary sinus. – Displacement of implant into the sinus may cause a foreign body reaction. – Use of decongestants with antibiotics and clearing off the etiologic factor is essential along with sinus drains.
- 24. PERSISTENT PAIN DUETO PROXIMITY TO CANAL • The patient may complain of severe pain post- operatively if the implant is in close proximity to the mandibular canal. • Retrieval of implant is the only solution left if the pain won’t subside by pain killers.
- 25. FAILED OSSEOINTEGRATION • Oneof the worst complications as it result in total retrieval of implants. Failure to follow complete sterilization protocols Contamination of implants either accidently or with gloves or fingers during placement.
- 26. Overheating during drillingabove 47 degree celcius in 1 minutes Decreased healing potential due to underlying systemic disease
- 27. CONCLUSION • Dental implantplacement procedure is not easy as it may seem. The procedure is always associated with a series of complication that can be prevented with proper planning, analysis and treatment. • There has to be thorough understanding of the anatomic area in preventing any complication. Careful selection of cases is mandatory while knowing the risks and avoiding them.
