AZ in Restorative Implant Dentistry Case 3: Maxillary Full Arch Overdenture and Mandibular Hybrid Bridge


Case Overview

In this restorative implant dentistry case, we will discuss the considerations and challenges involved in choosing between a maxillary full arch overdenture and a mandibular hybrid bridge. We will explore the factors that influenced the treatment plan and the steps taken to achieve a successful outcome.

Choosing an Overdenture for Lip Support and High Smile Line

One crucial factor in determining the treatment approach is the patient’s need for lip support and the presence of a high smile line. In cases where patients require enhanced lip support and have a more visible smile line, an overdenture is often the preferred choice.

The Mandibular Bone Resorption Challenge

In this particular case, the mandible presented with less bone volume than initially expected. Consequently, tooth extractions and bone grafting procedures were required to enhance the implant placement and support. These interventions were necessary to ensure the long-term success of the mandibular restoration.

Addressing Challenges in the Maxilla

The maxillary arch also posed its unique set of challenges. However, through meticulous planning and precise execution, the patient’s condition was significantly improved. After bone grafting and the placement of implants, a total of six implants were successfully integrated into the maxillary arch.

Focus on Function over Aesthetics

It’s important to note that in this case, the primary objective was to achieve a hybrid restoration that focused primarily on function rather than aesthetics. While aesthetic considerations are not overlooked, the primary goal was to restore the patient’s ability to chew, speak, and maintain oral health.

The Treatment Process

1. Initial Assessment and Treatment Planning

The initial assessment involved a detailed examination of the patient’s oral health, jawbone structure, and smile line. Based on the evaluation, a comprehensive treatment plan was devised, taking into account the patient’s specific needs and preferences.

2. Extraction and Bone Grafting in the Mandible

Due to the inadequate bone volume in the mandible, teeth that were beyond repair had to be extracted. Subsequently, bone grafting procedures were performed to augment the jawbone and create a solid foundation for implant placement.

3. Bone Grafting and Implant Placement in the Maxilla

Similar to the mandible, the maxilla also required bone grafting to enhance the bone structure. After the grafting process, implant fixtures were precisely placed to ensure maximum stability and support for the overdenture restoration.

4. Fabrication and Attachment of Overdenture and Hybrid Bridge

Once the implants had integrated with the jawbone, the restorative phase began. A custom-made maxillary full arch overdenture and a mandibular hybrid bridge were fabricated and securely attached to the implants. This process required skilled craftsmanship and attention to detail to create a comfortable and functional restoration.


Addressing the challenges presented by a maxillary full arch overdenture and a mandibular hybrid bridge requires a comprehensive treatment approach. By carefully considering the patient’s unique factors, such as lip support and smile line, and addressing bone deficiencies through grafting procedures, successful outcomes can be achieved. This case highlights the importance of collaboration between the dentist, surgeon, and lab technician in creating a functional and aesthetically pleasing dental restoration.

FAQs (Frequently Asked Questions)

1. How long does the bone grafting process in the mandible take?

The duration of the bone grafting process in the mandible varies depending on the complexity of the case and the patient’s healing response. On average, it can take several months for the graft to integrate with the existing bone.

2. Can a maxillary full arch overdenture provide the same functionality as natural teeth?

While a maxillary full arch overdenture can significantly improve chewing and speaking abilities, it may not offer the exact same level of functionality as natural teeth. However, advancements in dental technology have made overdentures more comfortable and efficient than ever before.

3. Is the hybrid bridge removable?

No, the mandibular hybrid bridge is a fixed restoration that is permanently attached to the implants. This ensures stability and allows for optimal function during daily activities.

4. How often should I visit the dentist after receiving a maxillary full arch overdenture?

Regular dental visits are crucial to maintaining the health and longevity of your overdenture. It is recommended to visit the dentist at least twice a year for check-ups, cleanings, and any necessary adjustments.

5. Are there any dietary restrictions with a maxillary full arch overdenture?

Initially, there may be some dietary restrictions to allow for proper healing and adjustment to the new restoration. Your dentist will provide specific guidelines, but generally, it is advisable to avoid hard and sticky foods during the initial stages of adaptation.
