Combination syndrome associated with a mandibular implant-supported overdenture: A clinical report

The Effect of Different Mandibular Dentures on Antagonistic Maxillary Ridge

“…15 This condition is usually associated with a mandibular distal extension removable partial denture and maxillary complete denture treatments in situations in which mandibular posterior prosthesis support is lost. 5,8 The result of the present study showed that, the amount of antagonistic maxillary bone resorption was significant when using the combined mucosa implant-supported mandibular complete overdenture, compared with that using mucosa-supported complete overdentures. This result was in accordance with the observation of Jacobs et al 15 and may be attributed to the increase of occlusal force of the combined mucosa implant-supported mandibular complete overdenture, compared with that using mucosa-supported one.…”

“…12 Several authors reported that the response of supporting soft tissues for implant overdentures and opposing prostheses was combination syndrome, 5,8,13 lack of maxillary denture stability, permits movement of the dentures that causes irritation and inflammation of the mucosa. The result of the present study showed a slight increase in the thickness of mucosa in the anterior region in the group having a conventional complete denture and in the group using bar-retained mandibular overdenture.…”

“…4 This condition is usually associated with mandibular distal extension removable partial denture and maxillary complete denture treatments in situations in which mandibular posterior prosthesis support is lost. [5][6][7][8] This situation can lead to the transference of significant occlusal forces into the anterior maxilla with subsequent maxillary alveolar bone resorption and soft tissue inflammation. 9 For several years, implant-supported overdentures have been used with excellent results in rehabilitation of the edentulous mandible.…”

Effect of Implant Position on Clinical and Radiographic Outcomes of Locator‐Retained Mandibular Overdentures: A 1‐Year Prospective Study

“…For completely edentulous patients wearing two‐implant overdentures, implants are usually placed in the interforaminal area of the mandible because of dense bone, sparse innervation, and lack of vital structures . This area improves denture retention and facilitates access for the patient and the clinician . In this area, the most commonly used positions for implant placement are canine and premolar areas .…”

Investigation of the implant-supported overdentures in completely edentulous mandibles

“…In such cases, it is important to prevent the anterior teeth from having occlusal contact at the centric occlusion position and to minimize contact in protrusive excursions. 29e31 Some studies have also suggested that the maxillary CD should be frequently relined or rebased to prevent combination syndrome, 29,32 whereas other studies have questioned whether combination syndrome would occur in such cases. 3,33 In this study, bone resorption necessitated that four maxillary CDs be relined over an average 6-year period.…”
