Sample SCFHS Dental Implant Practice Questions

Try these sample questions to review concepts for the SCFHS Dental Implant exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1According to the classical definition established by Brånemark, what histological feature defines successful osseointegration of an endosseous dental implant?

A.Direct structural and functional contact between ordered, living bone and the load-bearing implant surface without intervening fibrous tissue

B.Interposition of a thin, highly vascularized fibrous connective tissue capsule functioning analogous to a periodontal ligament

C.Formation of an amorphous calcified osteoid layer separated from the titanium oxide surface by active foreign-body multinucleated giant cells

D.Continuous deposition of secondary cementum and Sharpey fibers directly inserting into the microscopic surface pits of the titanium implant

Explanation: Osseointegration is histologically defined as the direct structural and functional connection between living, ordered bone and the surface of a load-bearing implant at the light microscope level. The absence of an intervening soft tissue layer or fibrous capsule between bone and implant is the hallmark of successful osseointegration.

2How do moderately rough titanium surfaces (average roughness Sa between 1.0 µm and 2.0 µm, such as sandblasted and acid-etched surfaces) compare to smooth, turned/machined surfaces in bone healing?

A.They stimulate rapid distance osteogenesis by inhibiting osteoblast adhesion and repelling initial blood clot formation

B.They promote superior fibrin retention, platelet activation, and contact osteogenesis, accelerating bone-to-implant contact

C.They completely eliminate bacterial colonization and biofilm formation compared to turned machined titanium surfaces

D.They reduce the required initial insertion torque by producing an elastic cushion of unmineralized osteoid along the implant body

Explanation: Moderately rough surfaces (Sa 1.0–2.0 µm, produced by sandblasting and acid-etching) enhance initial blood clot adhesion, platelet activation, and osteogenic cell migration directly onto the titanium surface, facilitating contact osteogenesis. This microtopography yields significantly higher bone-to-implant contact (BIC) and removal torque values compared to turned, machined surfaces.

3What is the primary biological mechanism by which platform switching preserves crestal bone around dental implants?

A.Allowing direct mechanical compression of the alveolar crest by an oversized prosthetic healing abutment

B.Eliminating the need for a biological width by preventing junctional epithelial attachment to the abutment surface

C.Moving the microgap and its inflammatory infiltrate inward, away from the crestal bone

D.Creating a hermetic chemical weld between the titanium implant body and the cobalt-chromium restorative coping

Explanation: Platform switching uses an abutment whose diameter is narrower than the implant platform. This inward horizontal mismatch shifts the implant-abutment junction (microgap) and its surrounding zone of inflammatory cell infiltrate (inflammatory connective tissue band) away from the outer crestal bone, significantly reducing crestal bone remodeling.

4Which mechanical feature distinguishes an internal conical (Morse taper) connection from an external hex butt-joint connection?

A.A completely flat mating interface that relies entirely on abutment screw tension to resist rotational and lateral shear stresses

B.A coronal indexing mechanism that requires high-viscosity cement to seal the microscopic vertical discrepancy between components

C.An external stabilizing collar that positions the highest mechanical stress concentration within the trabecular marrow space

D.A wedge-locking friction-fit that provides superior resistance to lateral bending forces and creates an effective bacterial seal

Explanation: Internal conical connections (Morse taper) feature an angled internal taper (typically 1.5° to 12°) that creates a friction-fit cold weld under torque. This geometry provides exceptional resistance to lateral bending moments, reduces micro-motion, minimizes abutment screw loosening, and establishes a tight seal that impedes bacterial microleakage.

5When placing an implant in soft, low-density trabecular bone (Lekholm & Zarb Type IV), which implant macro-design feature is most advantageous for achieving adequate primary stability?

A.A tapered body with aggressive, deeper apical threads that produce lateral bone condensation during insertion

B.A cylindrical, parallel-walled body with shallow microthreads extending uniformly to a blunt apex

C.A completely smooth, non-threaded press-fit design requiring under-preparation of the osteotomy site

D.A reverse-threaded coronal collar designed to induce intentional microfractures in the cortical plate

Explanation: In low-density Type IV bone (common in the posterior maxilla), a tapered implant geometry combined with aggressive, deep threads compresses and condenses the soft trabecular bone laterally as the implant advances, maximizing mechanical interlocking and primary stability.

6What is the primary biological benefit of chemically modified, hydrophilic sandblasted and acid-etched titanium surfaces (such as SLActive) compared to standard hydrophobic SLA surfaces?

A.Complete inhibition of osteoclastic activity during the first six months of functional occlusal loading

B.Faster protein adsorption and earlier osteogenic cell recruitment, shortening healing

C.Formation of an impermeable titanium nitride glaze that prevents osseointegration until week twelve

D.Spontaneous proliferation of periodontal ligament progenitor cells from surrounding vascular endothelial walls

Explanation: Hydrophilic modified surfaces maintain high surface energy by being stored in isotonic saline under nitrogen, preventing atmospheric hydrocarbon contamination. Upon placement, they promote immediate, complete blood wetting, rapid fibrin network formation, and earlier osteogenic differentiation, shifting the stability dip earlier and allowing safe loading protocols as early as 3 to 4 weeks.

7A 54-year-old patient with type 2 diabetes mellitus is evaluated for implant therapy. Which glycated hemoglobin (HbA1c) level represents the widely accepted clinical threshold above which elective implant placement should generally be postponed until improved glycemic control is achieved?

A.HbA1c > 5.5%

B.HbA1c > 6.2%

C.HbA1c > 8.0%

D.HbA1c > 4.8%

Explanation: While well-controlled diabetics (HbA1c < 7.0–7.5%) demonstrate implant survival rates comparable to non-diabetics, an HbA1c > 8.0% is associated with impaired microvascular perfusion, altered neutrophil chemotaxis, delayed bone healing, and significantly higher rates of early failure and peri-implantitis, warranting postponement for medical optimization.

8A patient with multiple myeloma has received monthly high-dose intravenous zoledronic acid for the past 24 months. What is the clinical consensus regarding elective dental implant placement in this patient?

A.It is safe to proceed provided a three-day course of amoxicillin is administered perioperatively

B.It is safe to proceed if a serum C-terminal telopeptide (CTX) test result exceeds 100 pg/mL

C.It is indicated to prevent disuse osteopenia in the posterior mandibular quadrant

D.It is contraindicated due to a high risk of Medication-Related Osteonecrosis of the Jaw (MRONJ)

Explanation: High-dose intravenous antiresorptive therapy for cancer (such as monthly zoledronic acid or denosumab) carries a substantially elevated risk of medication-related osteonecrosis of the jaw (MRONJ) after invasive dentoalveolar surgery. AAOMS guidance advises avoiding elective implant placement in oncology patients receiving these drugs.

9A 60-year-old patient who underwent curative radiotherapy for an oropharyngeal carcinoma requests implant reconstruction in the irradiated mandible. Radiation dosimetry records confirm the site received a cumulative dose of 65 Gy three years ago. What is the primary clinical concern?

A.High risk of implant failure and osteoradionecrosis from hypovascular, hypocellular bone

B.Rapid peri-implant hypervascularity leading to excessive osteogenesis and mechanical ankylosis

C.Accelerated salivary remineralization causing spontaneous osseointegration failure within the first two weeks

D.No added risk, because three years have passed since radiotherapy

Explanation: Bone exposed to radiation doses exceeding 50 to 60 Gy suffers irreversible hypovascular, hypocellular, and hypoxic changes (endarteritis obliterans). Implants placed in bone receiving > 50–60 Gy demonstrate failure rates 2 to 3 times higher than non-irradiated bone and carry a substantial risk of triggering intractable osteoradionecrosis (ORN).

10How does chronic cigarette smoking (greater than 10 cigarettes per day) primarily influence the clinical outcomes of dental implant therapy?

A.It improves primary implant stability by inducing dense cortical bone mineralization secondary to nicotine exposure

B.It significantly increases early implant failure rates and doubles the long-term risk of marginal bone loss and peri-implantitis

C.It has no measurable effect on osseointegration if implants are placed with an insertion torque greater than 45 Ncm

D.It selectively protects against anaerobic peri-implant infections by reducing gingival bleeding and mucosal exudate

Explanation: Smoking impairs peripheral microcirculation via vasoconstriction, decreases polymorphonuclear leukocyte phagocytic function, and inhibits osteoblast proliferation and collagen synthesis. Heavy smokers experience a twofold to threefold increase in early implant failures, greater marginal bone resorption, and a significantly higher prevalence of peri-implantitis.
