Dental Implants Complications & Maintenance

Question 1

Peri-implant mucositis is best described as:

Accepted Answer

Reversible inflammation limited to the soft tissue around an implant without bone loss

Answer

Peri-implant mucositis is the implant equivalent of gingivitis — reversible soft tissue inflammation without bone loss that responds to improved oral hygiene.

Question 2

Peri-implantitis is distinguished from peri-implant mucositis by the presence of:

Accepted Answer

Progressive marginal bone loss with inflammation

Answer

Peri-implantitis involves active, progressive destruction of the supporting bone around a functioning implant in addition to soft tissue inflammation.

Question 3

The first-line treatment for peri-implant mucositis is:

Accepted Answer

Professional debridement combined with patient oral hygiene instruction

Answer

Since mucositis is biofilm-induced and reversible, professional cleaning around the implant combined with excellent home hygiene consistently resolves it.

Question 4

A screw loosening complication with an implant crown is most commonly caused by:

Accepted Answer

Insufficient torque or occlusal overload generating bending moments

Answer

Inadequate tightening torque or excessive occlusal forces — especially lateral interferences — are the most common causes of abutment or retaining screw loosening.

Question 5

Nerve injury (paresthesia) after mandibular implant placement is most often associated with:

Accepted Answer

Implant placement too close to or into the inferior alveolar nerve canal

Answer

The inferior alveolar nerve runs through the mandibular canal and can be compressed, stretched, or severed if the implant encroaches on this structure.
